2+(-5)+8


Open in App
Solution

Given that, 2+(-5)+8

First, we will add the integers with the same sign,

2+(-5)+8=2+8+(-5)

=10+(-5)

To add integers with different signs, subtract their absolute values and the sum obtained is positive if the positive integer's absolute value is greater.

Absolute value of 10=10=10

Absolute value of -5=-5=5.

10>-5

Therefore, the required sum =(10--5)

=(10-5)

=5

Final Answer: 2+(-5)+8=5
