We can check our subtraction with addition! st : Move the answer 29 to the top of the addition problem. 2 nd : Move the subtracted number 53 across to complete the addition problem.
Now were ready to add… rd: Add the tens – 1st: Add the ones: nd : Regroup the ten Dont forget to add the regrouped one!
