Number Topic Guide

Numbers are all around us. The numerals we use represent quantities and are used for counting, measuring and comparing amounts. Imagine how difficult it would be to follow a recipe or go shopping without numbers!

Humans have used numbers for thousands of years. The most common number system is base 10 (decimal) but computers work in base 2 (binary) meaning they only use 0s and 1s!
