What is the distributive property in multiplication?

Back

The distributive property states that a(b + c) = ab + ac. It allows you to break down one of the factors into smaller parts.

How can you use rounding to estimate products?

Back

Rounding involves adjusting numbers to the nearest ten or hundred to make multiplication easier. For example, rounding 59 to 60 and 79 to 80 gives an estimate of 60 x 80 = 4800.
