I don't know who recommends the Sharp, but the broken
(crushed screen) Casio fx-83WA that my kids both use
(hence the broken screen...) has x^y and x ROOT y,
10^x and log, e^x and ln, trig functions and their
inverses and the hyperbolic version, and standard
deviation. It has fractions too, which seems to
be the main obvious difference between that and
the fx-550 which I think I used an Uni.
