Percent Difference and Percent Change Confusion

Postby BlasianAsian » Sun Apr 15, 2012 4:39 pm

I know this is an easy concept for many, but I've been having trouble since day one whether or not to put that negative sign. Can someone please clarify this for me?

Well, if it goes down, then it should be negative, unless it's asking for percent decrease.
decrease/increase are always positive. At least in this contest.

Use your HP to do percent change; there is a %CHG key above TAN. I don't think I've ever missed one using my HP..
