Part 2 of 4
Key concepts
3 concepts
- 1
When subtracting 25 from 83, you can't subtract 5 ones from 3 ones, so you need to regroup.
- 2
Regrouping means taking 10 from the tens place and adding it to the ones place to make a larger number to subtract from.
- 3
After regrouping, 83 becomes 7 tens and 13 ones, allowing you to subtract 25 and get the answer 58.
Part 3 of 4
Practice
3 questions
Solve 62 - 38 using the regrouping method. Show your work by writing out the new tens and ones values after regrouping.
Write down a subtraction problem (using two 2-digit numbers) that requires regrouping to solve. Explain why regrouping is necessary in the problem you created.
