Let's work with integers! Integers come in three types: zero, whole numbers, and their opposites. Zero sits in the middle of a number line, which can be drawn horizontally or vertically. Whole numbers, which are positive integers, are to the right or above zero. Negative integers, which are the opposites of whole numbers, are to the left or below zero. Now that you know what to look for, put your knowledge to the test by completing this challenge!
