A bad sign...
Okay, here's the game:
_ 1 _ 2 _ 3 _ 4 _ 5 = 2
Now, using only "+" and "-" to replace the "_"s, make that a true statement.
Mr. Language Arts gave that to me during lunch today after one of our science teachers gave it to him...
He and I are STILL working on it... (Actually, I believe Mr. Language Arts gave up just as I was leaving today... but Mr. Teacher Leader took it over and was working intensely on it as I walked out the door...
Shane, James, Mal? You guys are the heavy number crunchers here, got any ideas?
Tio Pat? Got any tricks up your sleeve for this one?
I think the Science Teacher has us beat...

This has to be a trick...the solution must involve manipulating the original order or inserting some combination of "+" and "-".
I give up...can't wait to find out the solution!

Success.....Backwards ...forward..any combination plus or minus..won't
work....either the info is incomplete or you did this to drive us crazy...Success.

Spot on, Mal. :)
I had a note on my desk when I got in this morning, it read (In Japanese):
"Odd + Odd numbers= Even numbers, Even + Even numbers= Even numbers, Odd + Even numbers= Odd numbers Thus, this is impossible. Also, I posed this to the 2nd years, they are still working on it. Sincerely, Science Teacher."
Mr. Language Arts and I both felt suitably duped... Mr. Science Teacher grinned and alerted us that we should be better at math...
Well, thanks anyways, Andi, Tio Pat, Mal... I wish I could give you an answer to this other than "Here's a lesson in Mathematics..."
