## 🧠 Explanation & Tips:

- Subtracting 0: Any number minus 0 equals itself. (e.g., 7 - 0 = 7)
- Same numbers: Any number minus itself equals 0. (e.g., 8 - 8 = 0)
- Borrowing not needed here: All problems are single-digit subtrahends or result in non-negative differences — perfect for early learners.
- Check your work: You can verify by adding the difference + subtrahend = minuend.
Example: 13 - 4 = 9 → 9 + 4 = 13 ✔️
