What does order of oporation mean?

Order of operations refers to the rules that dictate the sequence in which mathematical operations should be performed to accurately solve an expression. The standard order is often remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). This ensures consistency and avoids ambiguity in calculations. Following these rules is essential for arriving at the correct answer.
