Right Tool

I have been struggling with a math assignment for a few days.  I kept running into problems with the calculator, it was needed for this assignment.  Anyway, we were playing with logarithms and on my Casio graphing calculator there were some things that seemed to be missing.  The letter e is used heavily and for some reason I could not find just an e on the calculator.  I'm sure there is a way to make it happen but I am not seeing it and have put multiple hours in just trying to find the right combination to get the appropriate answer. No luck, ever.  Today Makayla brought me in her TI-84 which is the calculator the class called for.  The Casio has been fine up to now but has been a bear trying to work this logarithm thing.  With the TI-84 it was a lot easier.  I guess that's what I get for rolling with the lower priced competitor.  The right tool makes the difference. It is certainly nice to have this assignment done now.  It is almost over.
