Tips to Learn Portuguese

Tips to Learn Portuguese Language Learning Tips for Portuguese Beginners ChaptersWhy You Should Learn to Speak PortugueseHow Can You Choose the Right Portuguese Lessons?Where Should You Look for Your Private Portuguese Teacher?The Price of a Portuguese ClassLearning to Speak Portuguese: Don't Forget to Study in Between LessonsPortuguese, in all of its versions, is spoken by more than 200 million people around the world, making them  the 7th most spoken language globally in terms of native speakers. It is  behind Mandarin, Hindi, English, Spanish, Arabic, and Malay.Portuguese uses the Latin alphabet, just as many other European languages do. Therefore, it is often thought to be an easier language to grasp than if you want to learn Russian, Arabic, or Korean for example.It doesn't matter if you want to be completely fluent, or just have a conversational level, the most effective processes for studying Portuguese are often the same as for any second language. This means that if you want to learn Italian, Spanish, or German, the best way to go about it doesn' t necessarily change that much.Nevertheless, there is not one perfect teaching method for everyone. Some will prefer strong discipline while others will be keen to rely on more relaxed methods to teach them.Throughout this article we will look at everything that you need to know in order to learn Portuguese in order to communicate with a native speaker in Portugal, Brazil, and even certain countries in Africa. Aside from that, it will be useful when you go for  Portuguese London shopping.Our platform is full of excellent Portuguese teachers who are waiting for you!The Price of a Portuguese ClassThe price of a Portuguese class varies enormously according to many criteria. For those who want to learn Portuguese on their own, without outside help, it is often possible to learn completely free of charge. But you can bet on slow progression and acquiring the language in a less safe way. For one, there is no one to ask about any doubts that you have.We believe that this method of learning can be a complement to enriching your linguistic skills, but that on its own, it will not make you bilingual, if that is your goal.There are several tips to note when it comes to the cost of a Portuguese class:Web-based courses tend to be cheaper, as do group classes (pooling costs),Courses provided by natives are on average more expensive. It is sometimes by paying the price of a native that we can learn more about Brazilian culture, or the history of Portuguese civilization,Great differences in price exist depending on the geographical zone: large cities remain more expensive than smaller urban areas due to transport being more expensive and there being higher living costs,On the outskirts of big cities, tutors generally give classes at lower prices.Learning to Speak Portuguese: Don't Forget to Study in Between LessonsDon't forget that you need to study between Portuguese lessons in order to give yourself the best chance of being successful. There are very effective methods when it comes the memorization process. From your first lessons in Portuguese, you will have to become familiar with your learning method of choice if you want to speak the language like a pro.Obviously you will need personal motivation in order to succeed in learning Portuguese, but you will also need to use of all the resources available to you to study in between lessons. If you don't study outside of your classes, you are more likely to forget what you have studied before the next lesson comes around.Many learning options exist, like systematically making notes  so that you don't get lost in the process of learning the language. To do this, the learner might want  to build a color code (ex: a certain color for a new word of the Portuguese vocabulary, a different color for an adjective or a pronoun etc...). The only rule will be to remain clear while noting the most useful information.Many applications also act as virtual teachers. These include Duolingo, which sets you learning goals , and Mosalingua, which introduces you to an innovative memory-based approach that will help you to revise knowledge when it is in the process of being forgotten. This methodology is based on scientific studies regarding  the forgetting curve. According to this approach, a notion, a word, or an idea must be reactivated intermittently in order to be permanently memorized.This student is despairing--but little does he know there are apps to help with that!Online solutions do not stop there and there are  many websites that will make it possible to study the basics of Portuguese for beginners, or more complex concepts for the more advanced student. Some sites even offer effective  pronunciation modules.Immerse yourself in the language and learn to speak Portuguese through Youtube tutorials, which are sometimes very detailed and helpful.Yes, in addition to more traditional studying methods such as textbooks, there are many solutions available to us. Choice is a luxury here, but be sure to use everything out there to increase your chances of success.In short:Having  learning objectives  will make it easier for your tutors to know what learning methods to use. For someone who just wants to learn and assimilate some Portuguese, the self-learning method can be a useful and effective approach. It will be more difficult for a learner who is looking for fluency in Portuguese.The important thing is to choose a tutor  with whom you feel confident and whom you can trust. The form of the learning is sometimes as important as the language itself (what you are learning).There are many ways to learn the language and they can be used in conjunction with each other (private tutor, group classes, applications to test your level or revise certain concepts, websites, forums to help to solve certain linguistic problems, etc.).In short, it's very easy to take Portuguese classes with a learning method available for every type of learner.

Z Score Example

Z Score Example Definition: - The units marked on the horizontal axis of the standard normal curve are obtained by z and are called the z score or z value. A specific value of z gives the distance between the mean and the point represented by z in terms of standard deviation. Note: - The values on the right side of the mean are positive and those on the left side are negative. The z score for a point on the horizontal axis gives the distance between the mean and the point represented by z in terms of the standard deviation. Z score formula: - For a normal random variable x, a particular value of x can be converted to its corresponding z value by using the formula Z= (x- )/ Where and are the mean and standard deviation of the normal distribution of x, respectively. Example: - Let x be a random variable with its mean equal to 40 and standard deviation equal to 5. Find the z score for 1) X=49 2) X= 55 Solution: - According to the problem the population mean and standard deviations are 40 and 5 respectively. Hence = 40 and =5. 1) For x= 49, z score =(x-)/ =(49 40) / 5 = 1.80 Therefor z score for x= 49 is 1.80 2) For x= 55 z score =(x-)/ = (55-40) / 5 = 3.00 Therefor z score for x= 55 is 3.00

History of French Cuisine

History of French Cuisine French Cusine Over the Years ChaptersColours of the Middle Ages Refined Dishes of the CourtGreat Cuisine of the 19th CenturyGourmet Cuisine of the 20th Century From its great Bordeaux wines to its fine cheeses, regional specialities and refined dishes France is known worldwide for the quality of its cuisine. Everyone from the home cook to the Michelin star chef makes France the home of quality, luxury gastronomy.This reputation for exceptional cuisine did not happen overnight; it has a long history behind it and is rooted in the specialities of every region and culture in France.The three centuries between the invention of the printing press and the Revolution are characterised by gastronomical discoveries.Spices from the East were already well known in Europe but new ones arrived from other parts of the world.The vegetable world is revolutionized by tomatoes, squash, beans and potatoes, helping to put an end to famines in many areas with poor soil.Coffee, chocolate and tea bring new tastes, and turkey arrives f rom India.If the Middle Ages eliminated the gap between the noble diet and that of the poor (who, if necessary, would go as far as eating rats), the century of Louis XIV somewhat reestablished them.On the contrary, cooks strived to demonstrate their abilities by preparing the most difficult dishes.Things like jelly, marmalade, jam, compote remained within the reach of the poor but dairy and meat was considered highly aristocratic.Certain inventions of the French gastronomy were kept for the rich: mayonnaise, Chantilly cream and champagne.In the Age of Enlightenment, society evolved around food. The inn or tavern where you could just go to drink gave way to restaurants where people could go out to eat.  Learn more about French cuisine during cooking courses.Great Cuisine of the 19th CenturyIn the 19th Century, the restaurant becomes a veritable institution and food critics start to emerge.Thanks to its rich gastronomic history, France sets the tone for good restaurants. People are no w more interested in flavour, taste and pleasure.Russian style service becomes the norm: guests are served individually dish by dish.Different monarchs across the continent start hiring French chefs, and apprentice chefs around the world dream of one thing: learning to cook in France!At the same time, scientists are working on hygiene and health issues. The first ideas of a recommended balanced diet start to appear.Meanwhile, refined gastronomy comes onto the scene. The universe of the professional kitchen becomes more complex as it grows: the brigade is born and each kitchen is split into sections (sauces, desserts etc.)Desserts are the order of the day, and thanks to their sweetness they become enormously popular. Crepe Suzette, poached pears and peach melba burst onto the food scene in the Capital!Gourmet Cuisine of the 20th CenturyThe Michelin Guide lists the world's top chefs (Source: Crystal Clear Communications)The inaugural guidebooks Michelin, Gault Millau, Hachette wine g uide, and Larousse Gastro honour top chefs and restaurants. These guides showcase the exceptional quality of French chefs.Traditional cuisine from the Romantic period still remains but it starts to give to way to creativity.To find some cooking classes London, check here.Trends start to move towards decentralisation, meaning regional cuisine is championed. Grandmothers’ recipes are heralded as real French cooking.Foods like oysters, foie gras and scallops, which were originally only available locally, become popular across the country.Just like the Nouvelle Vague of the cinema world, a wave of New Cuisine arrives to disrupt the French gastronomy scene in the 1970s.Healthy diets are introduced into society, but richer dishes like the Breton lobster marinated in brandy remain popular.Great chefs like Robuchon, Ducasse and Bocuse emerge onto the scene. The ‘savoir-faire’ (know-how) of French cooking became more and more well-known thanks to the growing number of televisions in pe oples’ homes.Molecular cuisine gains in popularity thanks to advances in science and techniques. Foreign influences continue to multiply and new Italian, Chinese and Fast-food restaurants pop up all over the country and new eating trends become popular  like vegetarianism, veganism and gluten-free.It’s no surprise then that in 2010 French gastronomy was recognised as a central part of French heritage by UNESCO.Now it’s your turn to try this famously good French cuisine for yourself!You can give it a go with these French recipes.

Factor the Polynomial

Factor the Polynomial Factor the polynomial is a very effective tool which is utilized in the factorization. In polynomial, poly means many so this tool can e used for any type, that is, it can be used to factorize monomial, binomial, trinomial or higher etc. This tool uses step by step instructions to factorize and also it is used to factorize by adapting all factorization rules and methods. The most important point here is to understand the applicability of formula to be used in different-different problems. Question 1:- Factor the following expression: - x^2 + 14x+ 49 Solution 1:- In this question given expression is x^2+ 14x + 49 This is basically a quadratic equation, so here we will us middle term splitting method, which is shown below That is: - x^2 + 7x + 7x + 49 = x(x+7) +7 (x+7) = (x+7) (x+7) So this is the required equation. Question 2:- Factor the following expression: - x^3 + 50x^2 + 50x+2500 Solution 2:- In this question given expression is x^3 + 50x^2 + 50x + 2500 There is basically no common factor in above equation for all four terms. But it is quite clear that there is some common factor between first and second term and also between third and fourth term. So we will take common accordingly Therefore x^3 + 50x^2 + 50x + 2500 = x^2 (x+ 50) + 50(x+50) Now we can see that (x+50) can be taken out So x^3 + 50x^2 + 50x + 2500= (x+50) (x^2 +50)

SAT Math Topics 5 Tips on What You Need to Know Before You Go - Private Tutoring

SAT Math Topics 5 Tips on What You Need to Know Before You Go Anna L Nov 1, 2018 Find a Top Rated SAT Math Tutor Near You! It's Simple and Secure - Get Real Results Fast. Find Expert Private Tutors at Reasonable Rates Today! InPerson or Online Online InPerson Want to know what are the new SAT math topics? The math section of the SAT is designed to test your knowledge on problem solving, critical thinking, modeling, algebraic functions and using tools strategically. Seems like pretty broad concepts doesn’t it? Don’t worry, this is your definitive guide on the exact SAT math review topics that are currently being covered. By the end of this article you will know what math is on the new SAT, and how to review for it effectively! SAT Math Review The SAT math topics are about getting real. The good news is that the SAT doesn’t test you on every single math topic you have ever had studied. Feel free to breathe a sight of relief. Instead, it selects areas deemed the most relevant in college courses and careers. The SAT Math test focuses on areas that play a large role in colleges and a variety of careers, therefore applying real world math. These focus areas are: Heart of Algebra â€" create, manipulate and solve algebraic equations. These questions center around linear equations â€" equations that involve two variables that change as stated by a consistent pattern. Problem Solving and Data Analysis â€" is all about being quantitatively literate. These questions require you to create and use a model, as well as understanding the difference between the model predictions and actual data collected. Passport to Advance Math â€" includes questions that require the manipulation of complex equations and functions that are typically needed in STEM-based careers. On top of these areas, the test also covers additional key concepts that don’t fall into any of the above categories. These include coordinate geometry, basic trigonometry, area and volume. 5 Ways to Review the SAT Math Topics 1. Know how to complete grid in questions Students are often given advice to learn the style of questions and the format of the test. But what does this mean when it comes to the SAT?   In the SAT math section there are multiple choice questions and grid-in questions. Answering multiple choice questions are fairly straightforward â€" simply select the answer you think is correct. Grid-in questions are different. These are questions where you are going to have to come up with the correct answer on your own.   Dont ask me why grid in is the terms used, I dont have that answer! 20% of the questions on the SAT math test are grid-in questions so it’s definitely worth your while to understand how they are answered. You are given the instructions for the grid-in answers, but reading them can waste a lot of time. Instead, familiarize yourself with the instructions on practice tests â€" the instructions are the same. This allows you to spend more time thinking about your answers on test day. 2. Become familiar with the provided formula sheet Many students breathe a sigh of relief when they hear they don’t have to learn every single formula. But that doesn’t mean you can rest easy. You still need to know when to use each formula. Even knowing where the formulas are located on the sheet will save you valuable time. Have the sheet available during every single revision session and refer to it regularly. Pin it somewhere for you to study on a regular basis â€" a mirror, the refrigerator, or on the back of the bathroom door! 3. Work backwards Sometimes it’s easier to start by looking at the multiple choice answers available. You may be lucky enough to rule out a couple of options straight away, but if not, try putting the various options into the equation. This tactic has potential to actually be more time consuming, so may not be ideal for every question, but it’s certainly a good one to have in your bag of tricks. 4. Use the daily practice app The College Board not only provides official practice tests, but also an app to help track your progress. You will receive a question each day with hints and explanations. It’s a great way to maintain your math skills and to remind you to keep preparing for your math SAT! 5. Make the most of other subjects It may come as no surprise that you use math skills in a variety of subjects. Because the SAT math section has such a focus on real world math, subjects such as science and social science are incredibly relevant. Apply your math knowledge in these subjects and you are unknowingly preparing yourself for the SAT math test. Any questions that involve data analysis, graphs, percentages, ratios and tables are useful in preparation for the SAT. Topics Covered in the New Math SAT As you have already learned, the math SAT covers three main topics, with anything leftover categorized under additional math. This section will give you a SAT math topics breakdown, providing you with a thorough understanding of exactly what math is on the SAT. Heart of Algebra In this section, questions are focused around equations based on real-world topics such as distance, speed, mass, volume or everyday financial topics. Questions may ask you to; Solve linear equations and linear inequalities Interpret linear functions Answer equation word problems Graph linear equations Solve linear function word problems Solve systems of linear equations Answering these questions may require you to; Use multiple steps to simplify an expression or equation Select a graph that shows an algebraic equation that you saw in Algebra 1 course or Algebra 2. or choose the equation that describes a graph Indicate how a graph would be affected by a change in its equation You Might Also Be Interested in: How to Study Math: 35 Math Tips You Should Know Problem Solving and Data Analysis In this section, questions revolve around the application of ratios, percentages, and proportional reasoning. Weve come up with a collection of more topics and what might be asked of you below: Ratios, rates, percentages, units, and proportions â€" solve multi-step problems with a given ratio, rate, percentage or unit. You will also need to know how to calculate ratios, rates, percentages and units using the information provided. Table data and data inferencesâ€" analyze the data presented on a table and use it to answer questions Scatterplots â€" select the best equation to fit various scatterplots. Graphs and tables â€" understand and identify key features, as well as summarizing and evaluating the data presented in them Data collection and conclusions â€" determine whether data collection methods are accurate and reliable Statistics determine mean, median, mode, range, and/or standard deviation Passport to Advanced Math Students who are interested in STEM-based careers will need to pay particular attention to these type of questions. They involve complex equations and functions, and focus on the following areas; Solving quadratic equations Interpreting nonlinear expressions Quadratic and exponential word problems Radicals and rational exponents Operations with rational expressions and polynomials Polynomial factors and graphs Nonlinear equation graphs Linear and quadratic systems Structure in expressions Isolating quantities Functions Now that you are familiar with the new SAT math topics you can go ahead and prepare easily and aim to get the results that you need for schools!

Dicas para ninguém botar defeito! Será

Dicas para ninguém botar defeito! Será Image courtesy of  Carla S. FloresUma das minhas táticas para manter o conhecimento do idioma sempre atualizado é ler notícias em Inglês, muitas delas sobre o Brasil. Esta semana, no meu passeio semanal para ver o que o mundo fala do nosso país, me deparei com um artigo do The Guardian. A idéia por trás da matéria do jornal britânico é dar 10 dicas para que os turistas consigam gastar pouco e conhecer o país, sem sacrificar a sua segurança.Entre as coisas que achei mais curiosas está a indicação das comunidades do Vidigal e Tavares Bastos como bons locais para ficar hospedado no Rio.  Há uns anos atrás seria impensável, mas atualmente um jornal internacional aponta esses locais como boas opções para turistas. É um grande avanço, sem dúvida.Além disso, na parte sobre como viajar dentro do Brasil,  o pessoal do The Guardian recomendou que os turistas viagem de ônibus para longas distâncias. Isso, claro, se não comprarem passagens antecipadamente, já que em c ima da hora viajar de avião dentro do Brasil é caríssimo, e se tiverem tempo para se deslocar assim.Apesar de o foco principal da matéria ser no Rio de Janeiro, até falaram de outras regiões do país. Na minha opinião, pecaram ao dizer que São Paulo é sem graça, a não ser pela arte. Se até eu acho isso feio e sou carioca, imagina quem é de lá!Mas, mudando de assunto, quando falaram da comida cometeram uma gafe ainda maior. Tudo bem, no Brasil a gente come muito arroz, feijão e mandioca, mas não estou vendo nenhum vegetariano feliz em comer o nosso típico feijão com arroz. Segundo eles, tendo em conta esses três ingredientes, os vegetarianos ficariam felizes. Pensem comigo no momento em que um vegetariano encontra a carne do feijão. Outra, para comer na rua recomendaram milho cozido e coração de galinha. Quando foi a última vez que vocês comeram coração de galinha na rua? É que eu nunca comi!Estes foram apenas alguns exemplos do que eu achei caricato, mas r ecomendo a leitura do artigo. Acredito que é nesse tipo de matéria que a gente vê como a questão cultural é importante, não só quando estamos aprendendo um idioma, mas quando vamos visitar outro país. Claro que, em alguns casos, as matérias generalizam e partem de pressupostos errados. Outras, no entanto, são feitas com o maior cuidado. Adorava saber qual é a opinião de vocês sobre o artigo do The Guardian.
