Rules For Adding Integers
Adding integers means to carry out the operation of addition on two or more integers by putting an addition operator in between. There are three instances that need to be checked while adding two integers. Observe the table given below to see the details.
| Rule | Explanation | Examples | |
| Addition of two positive numbers | (+a)+(+b)=a+b | While adding two positive numbers we simply add both the numbers and get an answer which is a positive value, just like the addition of whole numbers. |
3+4=7
|
| Addition of a positive number and a negative number | a+(-b)=a-b | While adding a positive and a negative number, we take the difference of the absolute values of both the numbers and attach the sign of the greater number with the answer. |
4+(-5)=-1
|
| Addition of two negative numbers | (-a)+(-b)=-(a+b) | While adding two negative numbers, we take the sum of both the numbers and attach a negative sign with the answer. |
(-2)+(-4)=-6
|
Let us go through the following example to understand this better.
Solved Example:
Add the integers -8 and 12.
Solution:
We will use the second rule of adding integers.
So, -8 + 12 = 12 - 8 = 4
This means the sum of -8 and 12 gives 4.
Now, use the calculator and find the sum of the given integers.
- -9 and -3
- 5 and -7
