Visual Learning
Integers on a Number Line
Numbers increase as we move to the right and decrease as we move to the left.
Quick Notes
Remember These Points
- • Integers include positive numbers, negative numbers and zero.
- • Zero is neither positive nor negative.
- • On a number line, numbers increase from left to right.
- • Every positive integer is greater than every negative integer.
- • The sum of two integers depends on their signs and absolute values.
Practice
