When evaluating algebraic equations, which operation is performed first according to standard mathematical rules?

In algebraic evaluation, the order of operations is crucial for obtaining the correct results. The first operation performed is always the calculations inside parentheses. This is because parentheses indicate that the operations enclosed within them should be completed before any other operations, ensuring that their outcomes are factored into the larger equation.

By addressing operations inside parentheses first, you are essentially simplifying expressions in a way that respects their mathematical relationships. This foundational rule is often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). Thus, when evaluating an equation that includes parentheses, completing those calculations will dictate the subsequent steps in solving the equation accurately.
