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.
