What does the equation 4 x 30 = 120 tell us about multiplication?

Back

It shows that multiplication is commutative, meaning that the order of the numbers does not change the product. So, 30 x 4 also equals 120.

Front

What is division?

Back

Division is a mathematical operation where a number is split into equal parts. For example, 12 ÷ 3 means splitting 12 into 3 equal parts, which gives 4.
