Order of Operations
The order of operations, often abbreviated as PEMDAS, serves as a fundamental principle in mathematics, dictating the sequence in which mathematical operations should be performed within an expression. This set of rules ensures consistency and accuracy in mathematical calculations, preventing ambiguity and errors. By following the prescribed order, which prioritizes parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right), complex expressions can be simplified systematically. Understanding and applying the order of operations is crucial for solving mathematical problems accurately and efficiently, laying the groundwork for more advanced mathematical concepts.
