Introduction
Do you know what a positive and negative number is?A negative number is less than zero. When we write negative numbers we put a negative sign
before the digit. Sometimes negative numbers are called minus numbers – be careful not to confuse
these with subtraction. For example: -2 (this number has a negative sign before the digit).
A positive number is more than zero. Unlike negative numbers, you don’t need to put a sign in
front of positive numbers. For example: 3 (this number doesn’t have a negative sign before the digit).
