How would u use a calculator...?

Question

to multiply 23 and 32 if the "2" key doesnt work.

Please expplain .. help!

Answer 1

46 x 64 / 4

46 is twice 23 and 64 is twice 32. The answer will be larger by four times. So divide by 4.

Answer 2

8 x 4 x (31-8)

8 x 4 = 32

31 - 8 = 23

If both are multiplied, you'll get the same answer. Don't forget parenthesis on 31-8 though.
