Estimating Products

If you don’t need an exact result, you can estimate. To estimate a
multiplication, round some or all of the factors so that it will be easy to

multiply mentally. There are no hard and fast rules as to how exactly you

should round. The idea is round some of the numbers so that your new

rounded numbers are easy to multiply in your head.
