1. What is Decimal Multiplication?

Decimal multiplication is a fundamental arithmetic operation that calculates the product of two decimal numbers. It follows the same principles as whole number multiplication but requires careful placement of the decimal point in the result.

2. How Does the Calculator Work?

The calculator uses the multiplication formula:

Where:

• \( a \) — First decimal number
• \( b \) — Second decimal number

Explanation: The calculator multiplies the two input decimal numbers and displays the product with up to 4 decimal places for precision.

3. Importance of Decimal Multiplication

Details: Decimal multiplication is essential in various real-world applications including financial calculations, scientific measurements, engineering computations, and everyday shopping calculations.

4. Using the Calculator

Tips: Enter two decimal numbers in the input fields. The calculator will automatically compute and display their product. You can use positive or negative decimal values.

5. Frequently Asked Questions (FAQ)
