Subtraction with Regrouping
This document provides instructions for subtracting numbers with regrouping in 3 steps: 1. Write the minuend and subtrahend in columns 2. Begin subtracting from right to left, borrowing from the place value to the left when needed 3. Check the answer by adding the difference and subtrahend It then works through two examples step-by-step to demonstrate the process of regrouping when subtracting numbers.

- 6. Step 1:Write theminuend and subtrahend in columns. Step 2: Begin subtracting the ones then the tens and so on to the highest place value. (Regroup whenever necessary) Step 3: Check your answer.
- 7. 65 – 29= N
- 8. Step 1: Write theminuend and subtrahend in columns.
- 9. 65 – 29= N 65 -29
- 10. Step 2: Begin subtractingthe ones then the tens.
- 11. 65 – 29= N 65 -29
- 12. a. Subtract theones. 65 -29
- 13. a. Subtract theones. 6 5 -2 9 6 15 5 Since, we cannot subtract 9 from 5, we have to regroup, by borrowing 10 from 6 (number in the tens place). So, 5 + 10 = 15 So, 60 - 10 = 50 or 6-1=5
- 14. b. Subtract thetens. 65 -29 36 15 5

- 18. 205 – 48= N
- 19. 205 – 48= N 205 - 48
- 20. a. Subtract theones. 205 - 48
- 21. a. Subtract theones. 2 0 5 - 4 8 1 Since, we cannot subtract 8 from 5, we have to regroup, by borrowing 10 from the number next to it So, 0 + 10 = 10 So, 2 – 1 = 1 10 but since the number next to 5 is zero, we will borrow first 10 to the number beside 0, which is 2.
- 22. a. Subtract theones. 2 0 5 -4 8 7 15 1 Now, we can borrow from 10, 10 9 thus, 5 will become 15 and 10 will become 9
