Addition And Subtraction Of Integers

In addition and subtraction of integers, we will learn how to add and subtract integers with the same sign and different signs. We can also make use of the number line to add and subtract signed integers. There are certain rules for integers that have to be followed to perform operations on them.

Adding two positive integers results in positive integers, whereas adding two negative integers will result in the sum with a negative sign. But, the addition of two different signed integers will result in subtraction only and the sign of the result will be the same as the larger number has. See a few examples below:

• 2+2 = 4
• 2 + (-2) = 0
• -2 + (-2) = -4
• -2 – (-2) = 0
