[quote=Anonymous][quote=Anonymous]They got ten by doing the addition first, then the subtraction, at my last step. So 27-17 is 10. I am a middle school science teacher. [b]I thought with PEMDAS, When it comes to MD and AS, you do them in order. [/b]So the subtracting 27-12 would come before the adding 12+5. The online answe does not agree with me. I guess I could be wrong. That's just how I remember doing it. Granted, I havent gone over this in a long time![/quote] Yes, you do multiplication/division in order from left to right, and then you do addition/subtraction in order from left to right. It really ought to be P E M/D A/S[/quote]
