What is multiplication?

Back

Multiplication is a mathematical operation that represents the repeated addition of a number. For example, 3 x 4 means adding 3 four times (3 + 3 + 3 + 3 = 12).

What is division?

Back

Division is a mathematical operation that splits a number into equal parts. For example, 12 ÷ 4 means splitting 12 into 4 equal parts, which equals 3.

What is subtraction?

Back

Subtraction is a mathematical operation that represents the removal of one quantity from another. For example, 10 - 4 means taking 4 away from 10, which equals 6.
