The order of operations dictates the sequence in which operations are carried out in a math problem from "summary" of Maths Mate – 6 NEW by Madhubun
When solving a math problem, it is important to follow a specific set of rules known as the order of operations. These rules dictate the sequence in which mathematical operations should be carried out to ensure the correct answer is obtained. The order of operations consists of a set of rules that determine the priority of operations in a mathematical expression. The acronym PEMDAS is commonly used to remember the order of operations: parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right). Following the order of operations is crucial because without it, different people may interpret the same expression in different ways and arrive at different answers. By following the rules of PEMDAS, mathematicians and students can ensure that they are all solving the problem in the same way and obtaining the correct result. For example, consider the expression 2 + 3 x 4. If we do not follow the order of operations and simply calculate from left to right, we would get the answer 20. However, if we follow the correct order of operations and perform the multiplication before the addition, we would get the correct answer of 14. By consistently following the order of operations, mathematicians can avoid confusion and ambiguity when solving math problems. It provides a standard set of rules that everyone can follow to ensure that mathematical expressions are evaluated correctly.
