The Logic of Calculation
Modern mathematical solvers process expressions using precedence rules to correctly interpret the hierarchy of operations. This ensures that multiplication happens before addition, regardless of order. Whether solving a simple sum or a nested expression, following PEMDAS ensures universal consistency.
