Math 101
Don’t say we didn’t warn you. We told you in the previous chapter that we’d cover every math concept included on the GRE, and this chapter makes good on that promise. Yeah, Math 101 is long, very long, but you don’t necessarily need to read it straight through—it’s here as a resource to help you study any and all topics you need to review. If you’re good with triangles, by all means skip ‘em. If exponents have always baffled you, key in on that section. If you’ve never even heard of modes or frequency distributions—well, you’ll know what to do when you get to that part. If you’re a total super math genius, pass Go, collect \$200, and proceed right to chapter 3. (That’s just a Monopoly expression. No one’s really going to give you \$200.) Use as much or as little of what follows as you need, but make sure you have a good grasp of the concepts covered in this chapter if you want to ace GRE Math.
You’ll see that we have highlighted all the math formulas, which are integral to solving any GRE Math question in this chapter. Additionally, in the subsequent chapters, we have bolded all the math concepts that turn up in our explanations to the practice questions. That way, if anything seems difficult or particularly confusing, you can easily reference that particular math concept and come back here to get some targeted study.
As we discussed in chapter 1, GRE Math questions take many forms, but they all test one or more of four main subject areas:
1. Arithmetic
2. Algebra
3. Geometry
4. Data Analysis
We begin with one of the so-called three R’s of education, which for some reason doesn’t even begin with the letter “R”. . .
