Overview

Calculations and definitions are done when ‘=’ or ‘↻’ button is entered. All variables and function definitions are stored as text and evaluated only when needed. Each line is split into the first term and the rest. The first term is calculated and added to a stack. This reduction process is repeated recursively until the last term is handled. The rest of the lines are handled in the same way until the end of lines. Most of the mathematical functions yield one answer. However, some functions yield multiple answers with text explanation as needed. System-related commands are mixed with functions with the same format for consistency. Math keyboard is provided to program efficiently in addition to a system-level soft keypad. Reports and formulas can be shared through e-mails or other communication methods. Unit conversion, math quiz, memo, and programming capabilities are unique features among many others.
