In mathematics, the order of operations (PEMDAS/BODMAS) determines the correct sequence for solving expressions: Parentheses first, then Exponents, followed by Multiplication and Division from left to right, and finally Addition and Subtraction from left to right. For example, in the expression 5 + 3 * 2, multiplication must be performed before addition, resulting in 11 (not 16). Similarly, in 100 ÷ 5 * 2, operations are evaluated left to right, giving 40 (not 100 ÷ 10 = 10). This rule ensures consistent and unambiguous results in mathematical calculations.
