Multiplying and Dividing real numbers

Answer 1

To multiply and divide real numbers, follow these steps:

Multiplication:
1. Multiply the numbers as you would with whole numbers.
2. Determine the sign of the product:
- If the numbers have the same sign (both positive or both negative), the product is positive.
- If the numbers have different signs (one positive and one negative), the product is negative.

For example: (-3) * (-4) = 12

Division:
1. Divide the numbers as you would with whole numbers.
2. Determine the sign of the quotient:
- If the numbers have the same sign (both positive or both negative), the quotient is positive.
- If the numbers have different signs (one positive and one negative), the quotient is negative.

For example: (-12) / (-3) = 4
