In the previous segment, we discussed the addition of two negative integers. In this segment, we will look at the addition of two integers with different signs, that is a positive and a negative integer.

Addition of two integers with the same sign

Adding two integers with the same sign means adding two positive numbers or

adding two negative numbers.

In both cases, the absolute values of the integers are added, and the answer will take the sign of the integers.

Example	Sum of absolute values	Sign of the integers	Answer
2 + 3	|2| + |3| = 2 + 3 = 5	plus	5
−2 + (−3)	|−2| + |−3| = 2 + 3 = 5	minus	-5

Addition of two Integers with different signs

To find the sum of two integers with a different sign, that is, one positive number and one negative number, their absolute values are subtracted and the result takes the sign of the integer corresponding to the greater absolute value.

For example,

Q. 5 + (-3) = ?

Solution:

Method 1:

|−3| = 3 ??? |5| = 5

Now,

5 – 3 = 2
