Always try to use the inverse operation. Inverse operation is the opposite of your current operation. So if that problem is '2 x 10 = 20' Then you're going to use ' 20 (Divided by) 10' If it equals the first number, which is two, than your answer is correct. hope this helped :)

You can do 20/2=10 This helps because it is just doing the reverse so you know if you get it both ways that it is correct. Medal please?
