What is Integer?
Often referred to as directed numbers, integers are numbers that may be thought of as both positive and negative whole numbers.
There are an endless number of them, some of which are given below: I = {. . .,−3,−2,−1, 0, 1, 2, 3, . . .}. The standard symbol for describing integers is ‘I’.
There is an equal and opposite negative number for every positive integer. In actual life, integers are used to demonstrate that some values can be negative.
A temperature that is 25° below zero is represented by the symbol -25°, and one that is 17° above it is represented by the symbol +17°, or more simply by the number 17°.

How to Subtract Integers?
If you are familiar with adding integers, subtracting integers may be the easiest task for you. Because, despite the fact that subtraction is the operation, all you have to do in the entire process is add integers.
Below are methods that demonstrate how to subtract negative integers as simply as possible.
Step 1 : Whether the integers have similar or different signs (+,-), the first step is to convert the equation to addition form. We will accomplish this by replacing the operator with the ‘+’ sign and changing the sign of the second integer to the opposite sign.
For example, if you have the equation (+12) – (-14) =, you will change it into addition form. Initially, the operation will be changed from subtraction to addition +12 + (-14) =, and then the second integer’s sign will be changed to the opposite sign.
Since the second number (-14) in this case bears a minus (-) sign, we will simply replace it with a plus (+) sign, giving us (+12) + (+14) =. The equation has fully been transformed to addition form.
Step 2 : You only need to follow the standard steps for adding integers because you have already converted the equation into the addition form.
In case you missed it, adding integers was covered in a previous post. To review, if two integers have similar signs, simply add them and assign the result the common sign.
If the signs of the numbers differ, merely take the smaller value and subtract it from the larger value, then assign the result the sign of the larger value. Keep in mind that we are only discussing absolute values here when subtracting.
This may appear to be a little confusing. However, the examples below will clear up any confusion.
Example
1. Subtract Integers : (+11) – (+8)?
Solution :
First step is to convert the equation in addition form.
We have the original equation as, (+11) – (+8) =
When we convert it to addition form, we get :
∴ (+11) + (+8) =
Changing the sign of the second integer to the opposite sign, we get :
∴ (+11) + (-8) =
Now just perform the standard integers addition. Since the signs of the two integers differ, we will simply subtract the smaller value from the bigger one and apply the larger value’s sign to the result.
∴ (+11) + (-8) = 3. … (11-8 = +3, and result gets the sign of larger value)
The subtraction of integers (+11)-(+8) = 3.
Example
2. Subtract Integers : (-15) – (-3)?
Solution :
Converting the equation into addition form.
∴ (-15) + (-3)
The second integer’s sign is changed to the opposite sign.
∴ (-15) + (+3) = -12 … (15-3 = 12, and result gets the sign of larger value)
The subtraction of integers (-15)-(-3) = -12.
Example
3. Subtract Integers : (+12) – (-5)?
Solution :
Converting the equation into addition form,
∴ (+12) + (-5) =
The second integer’s sign is changed to the opposite sign and the integers are added.
∴ (+12) + (+5) = +17 … (12+5 = 17, and result gets the common sign as both the integers have similar sign)
The subtraction of integers (+12)-(-5) = +17.
Example
4. Subtract Integers : (-22) – (+7)?
Solution :
Converting the equation into addition form,
∴ (-22) + (+7) =
The second integer’s sign is changed to the opposite sign and the integers are added.
∴ (-22) + (-7) = -29 … (22+7 = 29, and the result gets the common sign as both the integers are negative)
The subtraction of integers (-22)-(+7) = -29.
