Math Operations with Negatives

Working with negative numbers can be tricky, but these basic rules will help you master them:

Addition and Subtraction Rules

Adding a negative number is the same as subtracting its absolute value.
Subtracting a negative number is the same as adding its absolute value.
Subtracting a positive number is the same as adding its negative counterpart.

Remember: Two negatives make a positive! This applies to both addition and multiplication.

Multiplication and Division

When multiplying or dividing negative numbers:

The product or quotient is negative if one number is negative.
The product or quotient is positive if both numbers are negative.

Negative Number Operations Examples
Operation	Example	Result
Addition	5 + (-3)	2
Subtraction	5 - (-3)	8
Multiplication	-4 × -6	24
Division	-12 ÷ 3	-4

Common Mistakes to Avoid

When working with negative numbers, these common errors can lead to incorrect results:

Sign errors: Forgetting to change the sign when adding or subtracting negatives.
Order of operations: Performing operations out of the correct sequence (PEMDAS/BODMAS rules).
Misapplying rules: Confusing the rules for addition/subtraction with multiplication/division.
Ignoring parentheses: Not properly handling expressions inside parentheses.

Always double-check your work, especially when dealing with multiple negative numbers and different operations.

Real-World Examples

Negative numbers are used in many practical situations:

Finance

In accounting, negative numbers represent debts or losses. For example:

A company with a net loss of $500 would be represented as -$500.
If a company earns $300 but has a loss of $500, its net position is -$200.

Temperature

Negative numbers indicate temperatures below freezing:

If it's 5°C and drops by 3°C, the new temperature is 2°C.
If it's -5°C and rises by 3°C, the new temperature is -2°C.

Elevation

Negative numbers represent depths below sea level:

The Dead Sea is about 430 meters below sea level (-430 m).
Mount Everest is about 8,848 meters above sea level (+8,848 m).
