Question 6879
The rules for evaluating expressions is to do all raising to powers (and taking roots) first. You don't have any of these to contend with.
Second, you do all multiplication and division, first within any groups in parentheses and then left to right.
Third, you do all addition and subtraction, again left to right.
(Actually, left to right isn't necessary, but it's a good habit to get into.)

In your case, you need to multiply the 3(2) (giving 6) before you do the addition.
The final answer will surprise you. (By the way, when you did the addition first you got 8(2) which is 16. Numbers written one after the other means you multiply them. The parentheses are there to show that the number isn't 82.)
