How does the mnemonic 'PEMDAS' assist in mathematics?

• A. It helps memorize geometry principles
• B. It helps in remembering the order of operations
• C. It aids in solving differential equations
• D. It defines types of angles

Answer: (B)

The mnemonic 'PEMDAS' assists in mathematics by helping individuals remember the order of operations, which is critical for correctly evaluating expressions that involve multiple arithmetic operations. 'PEMDAS' stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). This order is crucial because it ensures that mathematical expressions are solved in a consistent manner, thereby avoiding ambiguity and errors. For example, in the expression \(3 + 4 \times 2\), following the order dictated by 'PEMDAS' leads to multiplying 4 and 2 first to get 8, and then adding 3 to get 11, rather than adding 3 and 4 first. This clarification helps students and practitioners accurately navigate and simplify mathematical problems, making 'PEMDAS' an invaluable tool in mathematics education.
