What are facts and a fib about PEMDAS?

PEMDAS is an acronym that stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right), which represents the order of operations in mathematics. A fact about PEMDAS is that it helps ensure consistent results when solving mathematical expressions. A common fib is that multiplication always comes before division; in reality, multiplication and division are performed from left to right as they appear in the expression.
