Mixed Double Digit Addition and Subtraction

The Mixed Double Digit Addition and Subtraction worksheet challenges 3rd graders to apply both addition with regrouping and subtraction with borrowing in a single practice session.

How to Solve Mixed Operations

Check the operation symbol before each problem. For addition, work right to left and carry when a column sum exceeds 9. For subtraction, borrow when the top digit is smaller than the bottom digit. Switching between these two algorithms within the same worksheet builds mathematical flexibility.
