GMAT Number Properties: Divisibility and Remainders
Welcome back to our series on number properties. In this article, we deal with the fallout of failed divisibility: remainders. Remainders exist whenever an integer is divided by another integer that is not one of its factors. When integer n is divided by integer x,...
GMAT Divisibility Rules
Welcome back to our series on number properties. Last time we got familiar with prime factors as the substance of divisibility. In this article, we will extend this understanding by highlighting logical rules that sometimes come into play on GMAT number properties...
GMAT Number Properties: Divisibility and Prime Factors
Welcome back to our series on number properties. In this article, we cover the heart and soul of number properties: divisibility, specifically as it relates to the prime factors of integers. Here’s the all-important fact: Divisibility boils down to shared primes....

Exponents on The GMAT/EA: Everything You Need To Know
Understanding Exponents A key piece of algebraic notation on GMAT and Executive Assessment (EA) quant problems is the exponent. Exponents appear on many kinds of quantitative problems, so fluency with exponents (and radicals) is an indispensable skill for achieving a...
Large Exponents and The Units Digit
Welcome to the final article in our series on exponents. Some GMAT and Executive Assessment (EA) quant problems feature impossibly large numbers like 287459. These are problems that you simply can’t hope to solve without a key piece of knowledge that we call units...

Welcome to the penultimate article in our series on exponents on the GMAT/Executive Assessment (EA). Today we explore a problem category in which exponents are used to notating the highest power of an integer by which a larger integer is divisible. GMAT/EA problems...
Zeros and Nonzeros
Welcome back to our series on exponents. Last time we used powers of 10 to express “almost integer” numbers. Today we will use powers of 10 to handle problems that ask us to count zeros or nonzero digits. These problems can be baffling if you haven’t learned about...
“Almost an Integer” Problems
Unless you do math as a career or a hobby, you probably prefer integers to non-integers. Whole numbers are easier for us to conceptualize. But a certain class of GMAT/Executive Assessment (EA) problems involves numbers that are almost integers. Generally, this nearest...
Powers of 10 and Scientific Notation

Exponent Properties in Data Sufficiency
Exponents have properties that make them ideal pieces for data sufficiency problems on the GMAT and Executive Assessment (EA) quant sections. We’ve surveyed most of these properties in our first four articles in this series, but a couple of key ones haven’t been...
Bases Between -1 and 1
Many GMAT and Executive Assessment (EA) exponent problems - especially data sufficiency ones - require you to consider fractional bases. By this I mean proper fractions with values between -1 and 1, not improper fractions whose numerators exceed their denominators....
Negative Exponents and Negative Bases
Welcome back to our series on exponents. Today we will see what happens when we throw negatives into our exponential expressions. We will explore both negative bases and negative exponents. First, the bases. The rule to remember for negative bases is that odd powers...
