Abjad numerals

Abjad numerals (also known as Arabic numerals) are a set of numbers (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) used for counting and writing down amounts. They were first used by Arabic people in the Middle East or North Africa thousands of years ago, and then spread all over the world. When you use these numbers, it is easy to add, subtract, multiply and divide, which makes math easier!
