I don't think order of operations is useful unless you go into a career like an engineer, accountant, or rocket scientist. You know when something isn't useful when your teacher can't find an everyday explanation besides doing it for a job or school. Order of operations is not useful unless you have an algebraic expression which aren't very useful either.
My question is how would you use this for a job. Let me ask my dad, who is a CPA(Certified Public Accountant), how he uses algebraic expressions which tie into order of operations. My dad said that he uses algebraic expressions everyday. He needs to find how much his clients need to pay the government for taxes. He would have three numbers and need six so, he would solve for the variables by using algebraic expressions. My dad says that in his job algebraic expressions are super useful.
...And there you have it! There are careers that need to understand algebraic expressions. SO PEMDAS is good to have knowledge of until you know you WON'T need it.
ReplyDeleteStill you never know....I had TWO careers where I didn't need it and then I BECAME a SIXTH GRADE TEACHER. Luckily I quickly "remembered" how to do it.
