Step-by-step solution for: 3 Digit Subtraction Worksheets
Let’s solve each subtraction problem step by step. We’ll go one at a time, subtracting ones first, then tens, then hundreds — and regroup (borrow) when needed.
---
1) 362 – 148
- Ones: 2 – 8 → can’t do, so borrow from tens. Tens become 5, ones become 12. 12 – 8 = 4
- Tens: 5 – 4 = 1
- Hundreds: 3 – 1 = 2
→ 214
---
2) 417 – 253
- Ones: 7 – 3 = 4
- Tens: 1 – 5 → can’t do, borrow from hundreds. Hundreds become 3, tens become 11. 11 – 5 = 6
- Hundreds: 3 – 2 = 1
→ 164
---
3) 706 – 322
- Ones: 6 – 2 = 4
- Tens: 0 – 2 → can’t do, borrow from hundreds. Hundreds become 6, tens become 10. 10 – 2 = 8
- Hundreds: 6 – 3 = 3
→ 384
