How do you multiply a two-digit number by a one-digit number?

Back

To multiply a two-digit number by a one-digit number, you can use the distributive property. For example, to calculate 23 x 4, you can break it down: (20 x 4) + (3 x 4) = 80 + 12 = 92.

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 = 6 x 4 = 24 and 2 x (3 x 4) = 2 x 12 = 24.
