Column Subtraction: Subtracting 2-Digit Numbers

The video tutorial explains the process of column subtraction using three examples: 87 - 52, 64 - 47, and 92 - 83. It emphasizes the importance of aligning numbers correctly by tens and ones and demonstrates how to handle cases where borrowing is necessary. Each example is broken down step-by-step to ensure understanding of the subtraction process.
