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
