content: This programmable, handheld, symbolic graphing electronic calculator has a black plastic case and cover. An alphabetic (qwerty) keyboard is on the bottom left, and a numeric keyboard like that of an ordinary electronic calculator is on the right. The display is above the alphabetic keyboard and function keys are on both sides of it. These function keys operate a toolbar on the screen that brings up pull-down menus on the screen. For example, pushing the F2 function key brings up such “algebra” commands as solve, factor, expand, zeroes, approximation, common denominator, proper fraction, trigonometry, complex, and extract. It is possible to split the display, showing, for example, functions on one side and their graphs on the other.
