QUESTION 5:
What is the result of the following?
10 + 3 * 3 + 5
2 * 3 + 1 = 6 + 1 = 7 --+-- | higher priority than +, do first
When there are two or more operators of different priority, do the highest priority operator first. If there are several operators of the same priority do the operators from left to right. (Except for exponentiation, ^, which is done right to left.) Examine the following:
4 + 3 * 4 + 2
4 + 3 * 4 + 2 --- pick the highest priority operator
-----
4 + 12 + 2 --- all operators are of same priority
------ so do them left to right
16 + 2
18
Since * has the highest priority it is done first.
After doing * there are two + operators left. These are done left to right (although in this case it does not make a difference.)
