### What Your Math Teacher Didn’t Tell You About PEMDAS

*Did you know that you can attend the first session of any of our online or in-person GMAT courses absolutely free? We’re not kidding! **Check out our upcoming courses here**.*

**Here’s a phrase that might bring back some memories from middle school math class: Please Excuse My Dear Aunt Sally, or PEMDAS. (If you went to school outside of the U.S., you may have learned the acronym BEDMAS or BODMAS, instead.) You use this phrase to decide what order to do mathematical operations in: Parentheses first (from inside to outside), then Exponents, then Multiplication and Division (left to right), then Addition and Subtraction (also left to right). **

PEMDAS isn’t terribly fancy stuff. It’s just a useful little tool that helps us communicate clearly—it’s what tells us, for instance, that “2x(3+4)” means something different from “2×3 + 4.” But if there’s one thing the GMAT loves, it’s making things look more complicated than they really are.

### FAST Math for the GMAT (Part 5 of 5)

*Did you know that you can attend the first session of any of our online or in-person GMAT courses absolutely free? We’re not kidding! **Check out our upcoming courses here**.*

Welcome to the fifth and final installment of our Fast Math series. (Miss any earlier ones? Start here.)

Make your life easier on the GMAT: do less Math. (Yes, with a capital-M. ☺) I use Math-with-a-capital-M to mean formal, textbook math.

Sure, you’re going to have to do some textbook math on the GMAT, but it’s really not a math test. Business schools don’t expect you to have to do paper math in b-school or the real world. Rather, they’re testing how you think about math. And thinking about math in the real world is a lot different than textbook, school-based math.

For one thing, the correct answer on the GMAT is never actually a number or a math term. The correct answer is just (A), (B), (C), (D), or (E). *How* you get to that correct letter doesn’t matter in the slightest.

Okay let’s dive into our 5th Principle for Fast Math! Read more

### How Many GMAT Problems Do I Need to Solve?

*Did you know that you can attend the first session of any of our online or in-person GMAT courses absolutely free? We’re not kidding! **Check out our upcoming courses here**.*

**That’s a good question! Do you ***really* need to solve all the GMAT problems in the *Official Guide to the GMAT* in order to score a 700? What about the other side of the issue: is it possible that there aren’t *enough* problems in the *Official Guide*? How many GMAT problems should you solve before taking the official GMAT?

Before I share my answer, let’s get some facts on the table. Read more

If you’re a non-native English speaker, you know that you’ll need to be extra careful with idioms and other constructions that native speakers just “know.” If you’re a native speaker, though, don’t think that you have a huge advantage! The GMAT test writers know the kinds of common errors that have crept into spoken language, and they’re going to try to trap you, too!
