Interpreting Results
When you perform calculations with negative and positive numbers, the results can be interpreted in different ways depending on the operation:
- Addition: Adding a negative number is the same as subtracting its absolute value. For example, 5 + (-3) = 2.
- Subtraction: Subtracting a negative number is the same as adding its absolute value. For example, 5 - (-3) = 8.
- Multiplication: Multiplying two negative numbers gives a positive result. For example, -3 × -4 = 12.
- Division: Dividing a negative number by a positive number gives a negative result. For example, -10 ÷ 2 = -5.
Understanding these rules will help you interpret the results correctly and use them in your calculations.
