Question

What’s one way to check the answer to 5x6=30

Answer 1

You can check it buy turning the multiplication sentence into a division sentence, which would be 30/6=5 or 30/5=6

Answer 2

 5 x 6 = 30

If there are 6 groups of 5 apples each, do they add up to 30?
5 + 5 + 5 + 5 + 5 + 5
 10 +      10    +   10
      20    + 10
           30

True

hope this helps
