Three-Digit Subtraction with Regrouping

The video tutorial explains how to perform three-digit subtraction with regrouping. It provides two examples: subtracting 296 from 472 and subtracting 178 from 365. In each example, the process of regrouping tens and hundreds is demonstrated to handle cases where the top digit is smaller than the bottom digit. The tutorial emphasizes understanding the regrouping process to solve subtraction problems accurately.

What is the first step in three-digit subtraction with regrouping?

• Add the numbers

• Subtract the tens

• Subtract the hundreds

• Subtract the ones

In the example 472 - 296, why do we need to regroup the tens?

• Because 4 is less than 2

• Because 2 is less than 6

• Because 6 is less than 7

• Because 7 is less than 9

After regrouping, how many ones do we have in the example 472 - 296?

• 10

• 8

• 12

• 6

In the example 472 - 296, what is the result of subtracting the tens after regrouping?

• 5

• 8

• 7

• 9

What is the final result of 472 - 296?

• 206

• 196

• 186

• 176

In the example 365 - 178, why do we need to regroup the ones?

• Because 5 is less than 8

• Because 6 is less than 7

• Because 3 is less than 1

• Because 7 is less than 6

After regrouping, how many ones do we have in the example 365 - 178?

• 18

• 15

• 12

• 10

In the example 365 - 178, what is the result of subtracting the tens after regrouping?

• 8

• 9

• 7

• 6

What is the final result of 365 - 178?

• 197

• 187

• 217

• 207
