Subtracting Using the Crossing 10 Method

The video tutorial explains how to perform subtraction by crossing 10 using three examples: 14 take away 8, 22 take away 7, and 25 take away 9. Each example is broken down into steps, showing how to subtract ones first and then tens, using a number line for visualization. The tutorial aims to help students understand the concept of breaking down numbers to simplify subtraction.
