The simplified algebraic expression is
Explanation of Solution
Given information:
Concept Involved:
When adding integer with same sign we need find their sum and retain the sign of the larger number to the answer. When adding integers with different signs we need to find their difference and retain the sign of the larger number to the answer.
When subtracting integers, we need to change the subtraction problem to addition problem by changing the sign of the integer we are subtracting, then following the rules of adding integers.
When adding like terms we need to add their coefficients.
Calculation: Combine the like terms of the expression
Conclusion:
