Column Subtraction Techniques and Verification

The video tutorial explains how to solve the subtraction problem 373 - 95 using column subtraction and diagrams. It demonstrates the process of subtracting each column, starting with the ones, then the tens, and finally the hundreds, while using regrouping or borrowing when necessary. The final answer is verified using a diagram.

What is the first step in solving 373 - 95 using column subtraction?

• Subtract the tens column first

• Subtract the hundreds column first

• Start with the ones column

• Add 95 to 373

Why is regrouping necessary when subtracting 3 from 5 in the ones column?

• Because they are equal

• Because subtraction is not possible

• Because 3 is greater than 5

• Because 5 is greater than 3

What do you do when you cannot subtract 9 from 6 in the tens column?

• Add 10 to the tens column
