If you don't use PEMDAS when you are doing a problem for example 4+5(7*9)-6=? you will get the wrong answer. PEMDAS is in steps and you have to do the steps in order of course, and multiplication and division (whichever you see 1st and same for addition and subtraction). PEMDAS stands for "please excuse my dear aunt Sally"
