Tip

Remember that multiplying two negative numbers results in a positive number, while dividing two negative numbers also results in a positive number. This calculator handles these cases automatically.

Common operations with negative numbers

Negative numbers are used in various mathematical operations. Here are some common scenarios:

Addition with Negative Numbers

When adding a negative number to a positive number, subtract the absolute value of the negative number from the positive number. For example, 5 + (-3) = 2.

Subtraction with Negative Numbers

Subtracting a negative number is the same as adding its absolute value. For example, 5 - (-3) = 8.

Multiplication with Negative Numbers

Multiplying two negative numbers results in a positive number. For example, -3 × -4 = 12.

Division with Negative Numbers

Dividing two negative numbers results in a positive number. For example, -12 ÷ -3 = 4.

Practical examples

Here are some practical examples of how negative numbers are used in real-world scenarios:

Financial Calculations

In finance, negative numbers represent debts or losses. For example, if you have $100 and owe $50, your net worth is $50 (100 + (-50) = 50).

Temperature Conversions

Negative temperatures are common in many parts of the world. For example, converting -40°F to Celsius: (-40 - 32) × 5/9 = -40°C.

Elevation Measurements

Negative elevations represent depths below sea level. For example, the Dead Sea is approximately -430 meters below sea level.
