To evaluate: the givenexpression.

Answer to Problem 7CYU
The required value is 16
Explanation of Solution
Given:
Calculation:
Given the expression
Since, we have only two operations subtraction and addition, so according to the rules for order of operation,
Since on looking at the expression from left to right, first is subtraction and next is addition. So we will subtract first and then add.
Therefore we have that the numerical value of the given expression is
Conclusion:
Thus, the required value is 16
