The order of operations indicates a common set of rules for calculations. According to the order of operations, simplification of inner brackets and parentheses should come first if the equation contains symbolic groupings.
The order of operations is a rule that specifies the correct steps for evaluating mathematical expressions. PEMDAS helps you remember the order: parentheses, exponents, multiplication, and division (from left to right), addition, and subtraction (from left to right). Created by Sal Khan.
