📌 Key Tips for Decimal Addition/Subtraction:
- Always line up the decimal points vertically.
- Add trailing zeros if needed to make columns match (e.g., 5.3 → 5.30).
- Bring the decimal point straight down into your answer.
- Check your work by estimating (e.g., 7.9 – 3.47 ≈ 8 – 3.5 = 4.5 → close to 4.43 ✔️)
