Question

Which of the following is the *best* way to rewrite

44 x 50

so that the exact answer can be found mentally?

Answer 1

22 × 100

(which is 2200)

Explanation:

44 × 50 may not look like a problem you can do in your head. But if you notice that there is a 2 in the 44 that you can "move over" to the 50 instead, you totally can do this multiplication in your head.

44 × 50

= 22 × 2 × 50

= 22 × 100

= 2200
