Answer & Solution
Correct answer: A. The order of operations
1. Each capital letter in the saying stands for a step: Parentheses, Exponents, Multiply, Divide, Add, Subtract.
2. Those steps, taken in that order, are the order of operations for simplifying an expression.
3. Place value, divisibility tests, and variable names have no connection to the words in the saying.
