Subtracting 3-Digit Numbers with Regrouping

This video tutorial teaches how to subtract three-digit numbers by aligning them in columns. It provides three examples, explaining the process of borrowing from higher place values and addressing the issue of leading zeros in answers. The tutorial emphasizes the importance of aligning numbers correctly and offers practice problems for reinforcement.
