Why RedCrab?
No one today would want to work with word processing program that simulates a typewriter, for example, no copy, paste and edit. For typo errors, whole text must be rewritten.
But most PC calculators are just unflexible simulations of pocket calculators.
RedCrab is a calculator that exploits the possibilities of PC's. 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. Settings can be stored as a file in the prorams root directory instead in the PC' s Windows registry.
