Negative sign basics

A negative sign indicates a value that is less than zero. In calculations, negative numbers follow specific rules:

Adding a negative number is the same as subtracting its positive counterpart
Subtracting a negative number is the same as adding its positive counterpart
Multiplying two negative numbers gives a positive result
Dividing two negative numbers gives a positive result

Remember: A negative sign before a number means that number is less than zero. For example, -5 means five less than zero.

Worked example

Let's calculate 5 - (-3):

First, recognize that subtracting a negative is the same as adding a positive: 5 - (-3) = 5 + 3
Then perform the addition: 5 + 3 = 8

The result is 8.

Common uses of negative numbers

Negative numbers are used in various real-world scenarios:

Temperature measurements (below freezing)
Financial calculations (debts, losses)
Coordinate geometry (positions below the x-axis)
Scientific measurements (negative values)
