Let's solve each of the two-digit subtraction problems step by step. We'll follow the instruction:
subtract the ones first, then the tens, and use regrouping (borrowing) when necessary.
---
1) 43 - 25
- Ones: 3 - 5 → Can't do, so borrow 1 from tens.
- 13 - 5 = 8
- Tens: 3 (after borrowing) - 2 = 1
-
Answer: 18

2) 52 - 18
- Ones: 2 - 8 → Can't do, borrow 1 from tens.
- 12 - 8 = 4
- Tens: 4 (after borrowing) - 1 = 3

🔍 Explanation Summary:
- Always start with the
ones place.
- If the top digit is smaller than the bottom one,
borrow 1 from the tens place.
- After borrowing, subtract the ones, then move to the tens.
- This method ensures accuracy in two-digit subtraction.
