Subject: Order of operations

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,

real-life' 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

left-to-right, as long as we all agree to that? (As in "reverse Polish

notation" that I learned about years ago?)
