Mathematics has a special order of operations that's different from reading! Parentheses always come first because they group numbers together. Think of them as a mathematical container that must be opened first.
Then you follow the regular order: multiplication and division first (left to right), then addition and subtraction (left to right). But parentheses always take priority when they're present!
No! is completely different from . The first equals 12, but the second equals 22. Parentheses change the meaning!
You'll get the wrong answer! In this problem, working left to right gives 22 instead of the correct answer 12. Always look for parentheses first before starting any calculation.
Use the acronym PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. Or remember: Please Excuse My Dear Aunt Sally. Parentheses are always first!
