Understanding Negative Signs in Calculations
Negative signs indicate values below zero. In scientific calculations, they're crucial for representing:
- Temperatures below freezing (e.g., -5°C)
- Financial deficits (e.g., -$200)
- Scientific measurements in opposite directions
Key Rules for Negative Numbers
- Negative × Negative = Positive
- Negative × Positive = Negative
- Positive × Negative = Negative
- Negative ÷ Negative = Positive
- Negative ÷ Positive = Negative
- Positive ÷ Negative = Negative
Always include the negative sign when entering values to ensure accurate calculations.
Common Uses of Negative Numbers
Negative numbers have practical applications in various fields:
| Field | Example Use |
|---|---|
| Finance | Tracking account balances, profits, and losses |
| Science | Measuring temperatures, pH levels, and chemical concentrations |
| Engineering | Calculating forces in opposite directions |
| Everyday Life | Tracking expenses, debts, and temperature changes |
Worked Examples
Example 1: Temperature Calculation
If the temperature drops from 5°C to -3°C, what's the change?
Calculation: 5°C - (-3°C) = 5 + 3 = 8°C
Result: The temperature increased by 8°C
Example 2: Financial Calculation
If you have $100 and spend $150, what's your new balance?
Calculation: $100 - $150 = -$50
Result: You're $50 in debt
