Part of your task will be to come up with algebraic representations for these sets, or to understand what the given algebraic representation means.

## Key Properties of Integers for the GMAT

Data Sufficiency Integer Questions Data sufficiency questions have their own unique format, and thus their own way of testing you on integers. The question itself gives us a defined set of only integers, plus non-integers can neither be even nor a multiple of another integer.

These numbered chairs are a real-life example of a set of consecutive integers.

Below are all the rules you need to know. There are three different items, so the number of ways is 3! These ordering possibilities are also called permutations.
