What is PEMDAS?
PEMDAS stands for Parentheses, Exponents, Multiplication/Division (left to right), Addition/Subtraction (left to right). In the UK and other countries this is called BODMAS (Brackets, Orders, Division/Multiplication, Addition/Subtraction). Both describe the same order of mathematical operations.
Why Does Order Matter?
Without a standard order, 2 + 3 × 4 could equal either 20 (if you add first) or 14 (if you multiply first). PEMDAS standardizes this: multiply before adding, so the answer is 2 + 12 = 14.
