You guys that have these, how the hell did you learn them? Though powerful, and the RPN is cool, this is the most counter-intuitive POS I have ever used. I've spent the morning trying to write my own equations into it, and keep getting syntax or definition errors. I downloaded 800+ pages of manual, and still can't find a good procedure. My old TI was nothing special, but at least I could operate it. I'm not a CE or a programmer, I don't want to write my own code into it, but I don't think putting in a few equations for my Econ class is too much to ask.
