Question

What's one way we can check our answers to 2 times 10 equals 20

Answer 1

If you ever want to check an answer, do the inverse or reverse.

If you want to check that 2 x 10 = 20 do one of these two for examples:

20 divided by 10 or 20 divides by 2.

If either answer equals 2 for the first one or 10 for the other, than you know you have the right answer.

Hope this helps!
