### 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.

1. Take the first integer and change its operation from subtraction to addition.
2. Take the second number and get its opposite sign.
3. 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: 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: 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.

Example 4: 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
