Math has a special order called PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction). Parentheses always come first, no matter where they appear in the expression!
Solve each set of parentheses from left to right. For example: (5 + 3) - (2 + 1) = 8 - 3 = 5. Handle one set at a time!
Usually yes! In this problem, ignoring parentheses gives 27, but the correct answer is 13. Parentheses can completely change your result, so never skip them.
Think of parentheses as "Do me first!" boxes. Whatever is inside those boxes must be solved before anything else. Circle them if it helps you remember!
If you get the parentheses wrong, your whole answer will be wrong! Double-check your addition or subtraction inside parentheses before moving to the next step.
