 Current Topic:Microsoft Excel is WRONG!!! Beware... Ahhh, but you still have an error, Mr. devitg. As I stated in my earlier post, negation is just multiplying by -1.  To break down your example: -5*-5 can be written as -1*5*-1*5 and does indeed equal 25. However, -1*5^2  does not.  The 5^2 takes precedence according to the order of operations, then you multiply by -1 which gives the correct answer:  -25 Again, I ask you to check this on any mathematics program, in any algebra book or by talking to a good math teacher.  As I said before, if you are a premium member of this web site, you can use Mathematica to evaluate this one.  If you type in only -5^2, you get -25.   Do you think a program written for mathematicians by mathematicians under a company run by Dr. Wolfram, the guy who had his PhD in theortical physics at age 20, would do it wrong, while the program from a dropout from Harvard would do it right?  Yes I know Bill can add - he's got billions - but his subtraction needs some work...
