Has Math Order Of Operations Changed. As of 2007, wu wrote in “order of operations” and other oddities in school mathematics: The second person was arguing that.
We have a new math 6th grade series where order of operations has changed and pemdas is no longer the standard. The history of science and mathematics site seems like a better place to ask about when/how/if the order of operations has changed over time. If you change the order of operations, you will get a different result.
