Overview

In this chapter, we explore a new set of numbers called integers, which include both positive and negative numbers along with zero. While we are familiar with positive numbers like 1, 2, 3, etc., negative numbers like -1, -2, -3 help us represent situations such as loss, temperature below zero, or g

Key Concepts

When a larger number is subtracted

When a larger number is subtracted from a smaller number, the result is not a whole number. For example, 5 - 8 = -3. This requires the introduction of

Integers include all positive numbers (1

Integers include all positive numbers (1, 2, 3...), negative numbers (-1, -2, -3...), and zero. Zero is neither positive nor negative.

Integers can be shown on

Integers can be shown on a number line where zero is in the middle, positive numbers go to the right, and negative numbers go to the left. Each point

On a number line

On a number line, numbers increase from left to right. So, -5 < -2, and 0 > -3. Every positive integer is greater than every negative integer.

Addition and subtraction of integers can

Addition and subtraction of integers can be done using the number line. For example, (+3) + (-5) means move 3 right, then 5 left, ending at -2.
