## Category: SAT Math Section

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.

One of the ways in which the SAT math is changing—and this is a big change—is that there are only four answer choices on the redesigned test. Wait? That’s the big change? Well, I should add that the three wrong answers out of those four are pretty wrong. In other words, there aren’t really sneaky […]

Today, Dr. Gruber, renowned SAT expert and pioneer of the critical thinking strategies and skills necessary for standardized tests, shares 2 key strategies for tackling a tough SAT math problem. To begin, here’s an SAT problem that an enormous amount of students got wrong. In fact out of the 1,275,000 students who take the SAT, […]

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 […]

Oh, the dread ratio. Especially on geometry questions! How dare they not give us numbers!? Actually, sometimes ratios can make things easier. The same goes for percents. If you are only looking for the percent by which one thing is bigger than another, the actual numbers don’t matter. Just choose easy-to-work-with number(s). The ratio of […]

Bars and pies? Yum, pass the ice cream! Charts? Whoa, sounds like a fun new board game. Well, in both cases you are mistaken. The most common graphs featured on the SAT math are bar graphs and pie charts. Having a basic understanding of these two graphs can go a long way on the SAT […]

The SAT knows you know your basic exponent rules. But it also knows how to still trick you. In the midst of the test, stressed out and trying to finish before the proctor yells out the dreaded “stop”, you might flub something. Do you add exponents if you multiply (only if the bases are the […]

This is Mike McGarry, Magoosh’s GMAT Expert. As you may know, the GMAT is the entrance exam for business school. Believe or not, folks studying to be the business leaders of tomorrow don’t necessarily know any more math that you do! You see, some folks get to the end of whatever their last required math […]
