Understanding Subtraction Techniques

The video tutorial introduces subtraction for 4th-grade students, focusing on structured subtraction problems. It provides three examples, each demonstrating different techniques, including borrowing. The tutorial breaks down each problem into thousands, hundreds, tens, and units, guiding students through the subtraction process step-by-step. The aim is to help students understand and solve subtraction problems independently.
