What is the PEMDAS acronym used for?

The acronym PEMDAS is used to remember the order of operations in mathematics. This order dictates the sequence in which calculations should be performed to correctly solve mathematical expressions. Each letter stands for a different operation: P for Parentheses, E for Exponents, MD for Multiplication and Division (from left to right), and AS for Addition and Subtraction (from left to right). This systematic approach is crucial when evaluating complex mathematical expressions to ensure accuracy and consistency in results. By following the PEMDAS guideline, students and professionals can solve problems correctly and effectively.
