Here's a question that a student asked that has prompted an interesting discussion among our math teachers. He said, "Can you give me an 'everyday, reallife' example of where I would need to use the 'order of operations' that you're teaching us?" (Parenthese, exponents, mult/div, add/sub.)The teacher was stumped! Y'know what? So am _I_! I'm having a hard time coming up with a practical rationale for teaching/using the order of operations. Can some of you help? Isn't it possible that we COULD agree to do our math IN ORDER from lefttoright, as long as we all agree to that? (As in "reverse Polish notation" that I learned about years ago?)
