Splitting tasks questions are ones where you have two variables and you have to determine how many or how much of each variable is present within a given story problem or situation. Equivalent expressionsĪnother common type of difficult question you will face on the SAT Math exam is one asking you to find an equivalent expression.Įssentially, these questions ask you to look at an expression and see which multiple-choice solution is equivalent to the original expression. To successfully solve these math problems, you will need to be able to substitute the abstract figures with tangibles from the problem (ie: replacing t in the equation with the appropriate value of years using people or grams to represent the population or the remaining amount of a substance), and use exponential decay models. When you take the SAT Math section, you will see “story” problems asking you to solve exponential decay problems usually surrounding population density or radioactive substance decay. Working with radical expressions like these can be complicated, so it is important that you understand how to work with complex numbers. You might be asked to find the value of a when presented with a fraction and the value of i on your test, requiring you to rationalize the denominator to solve the problem. On the SAT Math section, you will also have to rationalize denominators that have complex numbers, represented by a+bi. Rationalizing denominators with complex numbers This question requires you to create and evaluate an expression using the properties of exponents, which can prove to be quite tricky during an exam. If f(x) = (2 – x)(x/3), and 4n = f(10), then what is the value of n? You are going to encounter questions that ask you to add, multiply, or divide exponents so that they are equal to one another and then factor them into an appropriate expression. Combining ace exponents and ace expressionsīefore you take the SAT, you will want to brush up on your exponents. Here are the top 10 hardest SAT Math questions you should look out for if you want to improve your score on the SAT Math section: 1. You will want to be ready to handle every type of math question that will come your way during the test if you want to raise your SAT score (or even get a perfect score!) With all of its fairly recent changes, the Math section of the SAT may seem more daunting than ever, but it can be conquered easily if you know what problems to prepare for when you take the test. When many test-takers attempt to improve their SAT score, the area they are most concerned about is the math section. When I raised my SAT score from average to perfect, I saw countless doors open for me: scholarship money, acceptance into prestigious schools, and opportunities that I never would have received without a high score.
