Multiplying
Multiply by applying the four-step decimal multiplication procedure:
- Determine the sign: The factors have different signs ( is negative and is positive), so the product will be negative.
- Write in vertical format and multiply as whole numbers: Align and on the right (ignoring decimal points). Multiply digit by digit: and (shifted one place left). Adding the partial products gives .
- Place the decimal point: Count decimal places in each factor — has decimal place and has decimal places, for a total of decimal places. Starting from the rightmost digit of , move places to the left to get .
- Apply the sign: Since the factors have different signs, the product is negative.
The result is .
