The Nadex C-270 is a battery-powered scientific calculator with over 360 built-in functions, including trigonometry, regression, permutations and standard deviation. It has a large dual-line black-and-white display that shows equations and outputs together, plus a basic graph visualization mode. It is aimed at students and teachers in math, engineering and science. Against rivals like the Casio fx-991 and TI-30X IIS, it offers more functions on paper but is not a full graphing calculator, and it lacks the track record those models have.
