So I bought a Casio 115ES and an HP Smartcalc 300s  Brian K  07282011 I purchased those two calculators for the purpose of picking one for my son to use in his upcoming school year. Well, I got them both and have now gotten around to opening them up, and to my surprise they're the exact same machine under the hood. Same screen, same buttons with the same functions. The Casio has a builtin equation solving function, the HP has arguable better aesthetics and buttons.
I guess I shouldn't have been surprised... At least they were cheap!

Casio fx115 ES offers numerical integration. Does Smartcalc 300s also?
Re: So I bought a Casio 115ES and an HP Smartcalc 300s  Brian K  07282011 It appears it does not.
Re: So I bought a Casio 115ES and an HP Smartcalc 300s  Gerson W. Barbosa  07282011 So it is more like the fx85 ES, perhaps.
Re: So I bought a Casio 115ES and an HP Smartcalc 300s  Brian K  07282011 That may be the case, I haven't had time to really dig into either of them.
I was simply struck by the fact that they initially appeared almost functionally identical.
Re: So I bought a Casio 115ES and an HP Smartcalc 300s  Gerson W. Barbosa  07282011 The fx115 ES has an outstanding numerical integrator, as discussed in this older thread: http://www.hpmuseum.org/cgisys/cgiwrap/hpmuseum/archv019.cgi?read=160194
I guess the Smartcalc 300s would cost a bit more if it were a rebranded 115es.
Re: So I bought a Casio 115ES and an HP Smartcalc 300s  Paul Gaster  07292011 The Casio also can solve a 2x2 or 3x3 system of equations, do some matrix math, solve a quadratic or a cubic equation, cross or dot product with vectors, work with complex numbers, and probably a few other things I have forgot. It's a nice calculator for the money.
