To Find: The sum

Answer to Problem 29SGR
Explanation of Solution
Given information:
Concept and Formula Used:
To add integers with same sign add their absolute value and put the sign positive if both are positive and negative if both integers are negative.
To add integers with different sign subtract their absolute value and put the sign of the greater integer.
Commutative and Associative property of addition.
Calculation:
The given sum is
Using commutative property
Using Associative property of addition
As the sign of both the integer is same therefore add the integers and both are negative sign of sum is negative.
As the sign of integer is different therefore subtract
The sign of the sum is negative as
