To evaluate: the given expression

Answer to Problem 29PPS
The numerical value of the given expression is 72
Explanation of Solution
Given:
a = 9, b = 4 and c = 11.
Calculation:
Given the expression
Since, there are three types of operations addition, subtraction and multiplication, so according to the rules for order of operation, by step 2, multiply first and then by step 3 since from left to right addition comes first in order, so after multiplication, add and then at lastsubtract.
Conclusion:
Therefore, the numerical value of the given expression is 72.
