Question

Suppose you want to find 30 X 30. How can you use a basic fact and breaking apart

Numbers to find the product of these multiples of 10?

Answer 1

900

Explanation:

To find 30 x 30 using basic facts and breaking apart numbers, you can break apart 30 into 10 x 3 and then multiply 10 x 3 to get 30 x 30. This can be done by multiplying 10 x 10 to get 100, multiplying 3 x 3 to get 9, and then adding the two together (100 + 9) to get the product of 30 x 30, which is 900.
