Mixed Triple Digit Addition and Subtraction

Designed for upper elementary students, the Mixed Triple Digit Addition and Subtraction exercise requires switching between addition and subtraction with three-digit numbers and complex regrouping.

How to Solve Mixed Operations

First identify the operation for each problem, then solve accordingly. Addition problems may require carrying across multiple columns, while subtraction problems may need borrowing across multiple places. Working carefully through both operations in one sitting strengthens your ability to approach any arithmetic problem with confidence.
