What does it mean for an equation to be balanced?

Back

A balanced equation means that both sides of the equation have the same value. For example, in the equation 8 x 1 = 4 x 2, both sides equal 8.

What is the product of 2 and 3?

Back

The product of 2 and 3 is 6, because 2 x 3 = 6.

Front

If 4 x 2 = 8, what is 2 x 4?

Back

2 x 4 is also 8. This shows that multiplication is commutative, meaning the order of the numbers does not change the product.

What is the missing number in the equation 8 x 1 = 4 x ____?

Back

The missing number is 2, because 4 x 2 = 8.

Front

What is the missing number in the equation 3 x 8 = 6 x ____?

Back

The missing number is 4, because 6 x 4 = 24, which is equal to 3 x 8.

What is the missing number in the equation 2 x 9 = 3 x ____?

Back

The missing number is 6, because 3 x 6 = 18, which is equal to 2 x 9.

Front

What is the missing number in the equation 2 x 2 = 1 x ____?

Back

The missing number is 4, because 1 x 4 = 4, which is equal to 2 x 2.

What is the missing number in the equation 4 x 10 = 8 x ____?

Back

The missing number is 5, because 8 x 5 = 40, which is equal to 4 x 10.

What is the associative property of multiplication?

Back

The associative property states that when multiplying three or more numbers, the way in which the numbers are grouped does not change the product. For example, (2 x 3) x 4 = 2 x (3 x 4).
