What does the acronym PEMDAS stand for in the order of operations?

• A. Please excuse my dear aunt Sally
• B. Perform each multiplication, division, addition, subtraction
• C. Please evaluate my distinct arithmetic sequence
• D. Prioritize every multiplication, division, addition, subtraction

Answer: (A)

PEMDAS is a mnemonic that helps students remember the order of operations used in mathematical calculations. The acronym stands for "Please Excuse My Dear Aunt Sally," where each initial corresponds to a specific operation in the order they should be performed: - P stands for Parentheses: Solve expressions in parentheses first. - E stands for Exponents: Next, handle exponents or powers. - MD stands for Multiplication and Division: These operations are performed from left to right in the order they appear. - AS stands for Addition and Subtraction: Finally, perform addition and subtraction from left to right. This phrase serves as a memory aid to ensure that calculations are conducted in a consistent and correct manner. Understanding PEMDAS is crucial for accurately solving mathematical problems, as performing operations in the wrong order can lead to incorrect results. The other choices do not accurately represent the correct operations or their sequence, making this mnemonic the most effective way to remember the order of operations.
