Checking Calculations Using Inverse Operations

The video tutorial explains the concept of inverse operations, which are used to verify calculations. It demonstrates how to use a 10s frame and a number line to check addition and subtraction problems. Examples include calculations like 12 add 5 and 8 add 7, showing how to reverse these operations to ensure accuracy. The tutorial also provides a practice problem for viewers to solve using inverse operations.
