What is the Order of Operations? Almost everything in this world follows a specific order. Things that don't follow an order are usually termed as disorganized or a mess. When solving number problems, specifically the ones with more than one operation in them, students cannot randomly perform operations as it will give an inaccurate answer. To solve a number problem that involves different operations, the students need to follow the PEMDAS rule. PEMDAS is an acronym that stands for Parenthesis, exponents, multiplication, and division, addition, and subtraction. To remember the order, a lot of students memorize the phrase, "Please excuse my dear aunt Sally." The order states that in a number problem, you have to always solve the part that is contained within parenthesis. The second step is to simplify the numbers with exponents or powers on them, and then move on to multiplication or\and division, and addition or/and subtraction. When multiplying, dividing, adding, or subtracting in a number problem, you need to proceed from left to right. This series of worksheets and lesson introduces students to the order of operations.
