The Order of Operations was first introduced in 1544 by Michael Stifel in his Arithmetica Integra. In the United States, PEMDAS is used to remind people of the order of operations. In other countries, BODMAS and BIDMAS are used instead. The Order of Operations helps you solve math problems with more than one operation in a step-by-step way.
