## 🔍 How to Solve These Problems (General Strategy):
1.
Line up the decimal points vertically.
2.
Add or subtract as you would with whole numbers, starting from the rightmost digit.
3.
Place the decimal point in the answer directly below the decimal points in the numbers.
4. If needed,
add trailing zeros to make decimal places match (e.g., 46.38 – 43.15 is fine; but 5.2 – 3.14 becomes 5.20 – 3.14).
This ensures accuracy and avoids misalignment errors.
