### Subtraction of Integers Possibilities

We will come across three different possibilities whenever we are solving any problem in this concept they are as follows.

- Subtracting two positive integers
- Subtracting two negative integers
- Subtracting one positive integer and one negative integer

### Rules to Subtract Integers

While subtracting any integer we need to follow a few simple rules. That is first we need to convert the given subtraction problem into an addition problem. To do so follow the below steps.

- Take the first integer and change its operation from subtraction to addition.
- Take the second number and get its opposite sign.
- Then finally proceed with the regular addition process.

### Rules to Subtract Integers Examples

**Example 1: **Subtracting two positive integers

Solve (9) – (12)

**Solution:**

Initially, we have to change the operation

That means subtraction becomes an addition

Now we have to change the sign of the second integer

Which gives us (9) – (12) = 9 + (-12)

= -3

**Example 2:Â **Subtracting one positive integer and one negative integer

Solve 25 – (-5)

**Solution:**

First of all, we have to change the operation

That means subtraction becomes an addition.

Now we have to change the sign of the second integer

Which gives us (25) – (-5) = 25 + (5)

= 30

**Example 3:Â **Subtracting one positive integer and one negative integer

Solve -46 – 20

**Solution:**

First, we have to change the operation

That means subtraction becomes an addition

Now we have to change the sign of the second integer

Which gives us -46 – 20 = (-46) + (-20)

= -66.

Answer: -66.

**Example 4:Â **Subtracting two negative integers.

Solve (-28) – (-8)

**Solution:**

First, we have to change the operation

That means subtraction becomes an addition

Now we have to change the sign of the second integer

Which gives us (-28) – (-8) = (-28) + (8)

= -20
