Step-by-step solution for: Subtraction by Regrouping Worksheets and Exercise - EngWorksheets
Let’s solve each subtraction problem one by one. Remember, we’re doing subtraction with regrouping — that means sometimes we need to borrow from the tens place when the top number in the ones column is smaller than the bottom number.
We’ll go row by row, left to right.
---
First Row:
1. 35 - 6
Ones: 5 - 6 → can’t do! So borrow 1 from tens.
35 becomes 2 tens and 15 ones.
15 - 6 = 9
Tens: 2 - 0 = 2
→ 29
2. 72 - 6
Ones: 2 - 6 → can’t do! Borrow 1 from tens.
72 becomes 6 tens and 12 ones.
12 - 6 = 6
Tens: 6 - 0 = 6
→ 66
3. 77 - 8
Ones: 7 - 8 → can’t do! Borrow 1 from tens.
77 becomes 6 tens and 17 ones.
