This worksheet helps kids understand addition and subtraction in a different way. One of the numbers is missing in each problem. Using the answer and the other number, kids reverse the operations—changing addition to subtraction and subtraction to addition—to find the missing number.

For more reverse addition and subtraction, check out the rest of the worksheets in the Find the Missing Numbers series.
