# Rules to Subtract Integers

The rules to subtract integers are discussed here.

If **a** and **b** are two integers, then to subtract **b** from **a**, we change the sign of **b** and add it to **a**;

*a – b = a + (-b)*

Consider the following examples for the rules to subtract integers.

### Find the difference of the integers:

**1. 4 from 9**

In order to subtract 4 from 9, we change the sign of 4 and add it to 9.

Thus, we have 9 – 4 = 9 + (-4) = 5.

**2. -4 from 7**

In order to subtract -4 from 7, we change the sign of -4 and add it to 7.

Thus, we have 7 – (-4) = 7 + 4 = 11.

**3. 3 from -8**

In order to subtract 3 from -8, we change the sign of 3 and add it to -8.

Thus, we have -8 – 3 = (-8) + (-3) = -11.

**4. -9 from -5**

In order to subtract -9 from -5, we change the sign of -9 and add it to -5.

Thus, we have -5 – (-9) = (-5) + 9 = 4.
