Subtraction with Multiple Regrouping Steps
Subtraction with Multiple Regrouping Steps
Subtract 836 – 647
Solution
Step 1:
Line up the numbers vertically.
Step 2:
In ones column, 7 is bigger than 6. So we borrow from 3 in tens column. We cross out 3 and write a 2. We put borrowed 1 beside 6 to make it 16. Then we subtract 7 from 16 to get 9.
Step 3:
In tens column, 4 is bigger than 2. So we borrow from left. We cross out 8 and write a 7. We put borrowed 1 beside 2 to make it 12. Then we subtract 12 – 4 = 8.
Step 4:
In hundreds column, we subtract 7 – 6 = 1. So final answer is 189
Subtract 658 – 379
Solution
Step 1:
Line up the numbers vertically.
Step 2:
In ones column, 9 is bigger than 8. So we borrow from 5 in tens column. We cross out 5 and write a 4. We put borrowed 1 beside 8 to make it 18. We then subtract 18 – 9 = 9.
Step 3:
In tens column, 7 is bigger than 4. So we borrow from left. We cross out 6 and write a 5. We put borrowed 1 beside 4 to make it 14. We then subtract 14 – 7 = 7.
Step 4:
In hundreds column, we subtract 5 – 3 = 2. So final answer is 279
