MTTC 103 Elementary Practice

The concept of the order of operations involves the rules that dictate the correct sequence to evaluate mathematical expressions. This sequence is often remembered by the acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

The inclusion of addition, subtraction, multiplication, and division in the correct answer reflects the complete set of fundamental operations that are used in arithmetic expressions. Each of these operations has a specific priority level, and when presented together in an expression, they must be calculated in the correct order to arrive at an accurate result.

This approach helps maintain consistency across mathematical calculations, allowing different people to arrive at the same answer when solving problems. In contrast, limiting the focus to only one or two operations, as suggested in other options, does not accurately represent the full range of arithmetic operations that are typically applied according to the established order of operations.
