The acronym PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction, which represents the correct order in which mathematical operations should be performed to ensure accurate results. According to PEMDAS, operations enclosed in parentheses should be calculated first, followed by exponents. Then, multiplication and division are performed from left to right, and finally, addition and subtraction are also carried out from left to right.

This order of operations is crucial because it helps avoid ambiguities in mathematical expressions. For example, in the expression 3 + 5 × 2, applying PEMDAS dictates that the multiplication is completed before the addition, resulting in 3 + 10, which equals 13 rather than 16, which would occur if addition were done first.

In contrast, the other choices misplace or incorrectly sequence the operations, which can lead to different and incorrect outcomes when solving expressions. Thus, understanding the correct sequence encapsulated in PEMDAS is essential for solving mathematical problems accurately.
