Easy to use like a pocket calculator, but provided with full screen editor, which supported corrections, saveing and printing as a word processing program. Several tasks can be written in the same worksheet. Results can be adopted in other mathematical problems as in a spreadsheet program. Images and texts can imported to describe complex calculations. Quick start without studying the manual The handling of the basic functions is just like a conventional calculator. There is no training required. Whoever can operate a pocket calculator can also use RedCrab without studying the manual. This guide describes fundamentally the advanced features which a normal calculator does not possess. RedCrab is portable RedCrab is fully portable. The program can be started from external data storage source without installation.
