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?)
