Manhattan Prep GMAT Blog - A Memorizable List of GMAT Quant Content (Quantent) by Patrick Tyrrell

Even though there’s no “new math” on GMAT Quant, there is still a ton of content to keep on our radar. And just like the tragic studying for a vocab test, we’ll have to learn 200 different things, even though the test is going to only ask us 31 of those things (because we don’t know which 31 things we’ll get asked on our test day).

One common complaint I hear from my students is that they ‘haven’t done math like this since high school.’ And they’re pretty much right: the concepts in the Quant section are by and large wrapped up by Algebra II. But for some subjects, my students drastically underestimate how long it has been since they’ve thought about them. One such subject: remainders on the GMAT. Read more

Manhattan Prep GMAT Blog - Stop Careless GMAT Quant Errors by Chelsey Cooley

Here’s a careless error that any of us might make:

x – 7 – 2x + 4 = 3x

-x – 3 = 3x

-3 = 2x

x = -1.5

Did you spot the error? If yes, give yourself a pat on the back and keep reading. If not, go back and review each step. This time, as you think through it, you can only use the terms added, subtracted, multiplied, and divided. On each line, identify which of those operations we used, and how we used it. Read more

Manhattan Prep GMAT Blog - What Your Math Teacher Didn't Tell You About PEMDAS by Chelsey Cooley

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.
