Below you’ll find some algebra practice questions like the ones you’ll find on the New SAT Math section.
In order to do even rudimentary algebra, you’ll need to understand how to combine like terms and, if the question asks to solve for a variable, how to isolate that variable. Below is a quick review to help you with these basics.
Important stuff first: 27 of the 58 questions or nearly half of the questions on SAT Math will be “Heart of Algebra” questions. Read on for what this means.
If you’ve watched the first part of this series (SOHCAHTOA: Part I), you might be asking yourself the following: Who cares what sine, cosine, and tangent stand for? The answer? YOU! This info will help you ace the new SAT and give you a leg up in your trigonometry class. Watch the video to learn!
Yes, there will be trigonometry on the new SAT. And while it won’t be easy, the trig covered on the redesigned SAT will be relatively basic, encompassing two main areas: the unit circle and sine, cosine, and tangent. Today, we’ll focus on one of the best tricks of trig: SOHCAHTOA. Enjoy the video!
Math Basics – Exponents You are likely to see a few exponents on the SAT. In order to have a chance on the harder questions, you’ll have to first know your basics. Once you are consistent at doing well on these, you want have to worry about exponents. The thing, though, is it is very […]
One of the most vital pieces of math information that I have given to students is not about math at all. It is about the language. The math section is not so much about math–as you know, you had covered most of the actual content by the time you were finished with ninth grade. What make this section especially difficult are the words of the question.
Sometimes we want to force an equation on to every problem with unknowns. However, catch yourself if you suddenly hit a wall. What does that feel like? You are desperately scrambling to write some kind of equation and all you get are a bunch of scribbles and the sinking feeling that nobody could solve this […]
Prime numbers are one thing. Combining them with counting principles is an entirely different thing together. Let’s say I have a two-digit number. All you know is that both digits are prime numbers. So you could have 53, 37, etc. But how do you actually count up all these numbers without having to list them […]
n = (10^10 x 9^9 x 8^8…3^3 + 2^2 + 1^1)^2 How many zeroes does n^2 contain? First off, you need to recognize the pattern: every number has an exponent equal to itself, i.e. 10^10, 8^8 , etc. That means, that the (….) represents 7^7 x 6^6 x 5^5 x 4^4. Now that we can […]
