According to the order of operations, we first solve the exercise within parentheses:
Now we solve the rest of the exercise:

Without parentheses, would equal 5 because we'd work left to right. The parentheses make happen first!
Think of PEMDAS: Please Excuse My Dear Aunt Sally. The 'P' for Parentheses always comes first in any math problem!
Solve each set of parentheses separately first, then continue with the rest of the problem. Work from the innermost parentheses outward if they're nested.
Yes! You can think: "What number minus 6 equals 1?" Since , we know our parentheses calculation of 6 is correct.
