![]() ![]() Use only the steps required to solve this particular problem.įirst, resolve any exponents. There are two numbers with exponents, the 4 and 2. ![]() There are various steps in the Order of Operations. PEMDASĪ frequently used expression in English to help students remember the order of operations is PEMDAS.Īnother way to remember this is the phrase “ Please Excuse My Dear Aunt Sally.” They are part of the same step, however, they can only be done after items in parentheses, exponents, and any multiplication and division. You can do subtraction first, or you can do addition first. Addition and SubtractionĪddition and subtraction also work together. In other words, it doesn’t matter if you do division or multiplication first, but they must be done after parentheses and exponents and before addition and subtraction. Multiplication and division can be done together. If there are exponents in the equation, these would be done next. In cases like this, work from the inside out. It is even possible to have parentheses within parentheses. The stuff inside the parentheses may also need to be broken down according to the order of operations as well. When there are parentheses, whatever is inside must be done first. The order of operations says that operations must be done in the following order: parentheses, exponents, multiplication, division, addition, and subtraction. Applying the Order of Operations (PEMDAS) It explains how to interpret an equation to mean what it is supposed to mean. The order of operations is like grammar rules for the language of math. The order of operations is the rule for what operations should be done first when there are several operations within the same equation. Similarly, when you multiply numbers together, you are performing the operation of multiplication. When you add two numbers together, you are performing the operation of addition on them. Operations are things like addition, subtraction, multiplication, and division. Break it down into parts using the order of operations and do a little at a time. ![]() ![]() Trying to do the entire equation at once can often lead to mistakes. For example, do the portion within the parentheses and then rewrite the equation. A good idea when working with many operations at a time is to do a little portion of the equation at a time, rewriting frequently. ![]()
