🔢 BASIC RULES FOR MULTIPLYING DECIMALS

⭐ Rule 1: Ignore the Decimal Points First

Multiply the numbers as if they are whole numbers.

📝 Example:
2.4 × 1.3 → multiply 24 × 13

⭐ Rule 2: Count the Decimal Places

Count how many digits are after the decimal point in both numbers.

📝 Example:
2.4 → 1 decimal place
1.3 → 1 decimal place
Total = 2 decimal places

⭐ Rule 3: Place the Decimal Point

In your final answer, move the decimal point from the right to the left based on the total number of decimal places.
