RedCrab The Calculator screenshotRedCrab is a reliable and comprehensive statistic, financial and scientific calculation solution which features a powerful formula editor. This editor is able to run in full screen mode and features a window which is similar to a sheet of paper, allowing you to easily introduce mathematical expressions.

RedCrab Calculator is a software capable of exploiting the entirety of your computer's possibilities. The program is simple to use, just like a pocket, yet powerful at the same time. This is possible thanks to its full screen editor, which is able to support saving, printing, and corrections, just like a word processing application. The editor also supports complex algebraic expressions, including exponents, fractions, variables, square roots, etc., which are used for technical and scientific applications.

RedCrab Calculator lets you write and perform several tasks into the same worksheet, allowing you to adopt the results in other mathematical problems. You can also import text and images for describing complex calculations.

RedCrab Calculator is also fully portable, being compressed in a single executable file. Because of this, the program does not require installation on the computer. You can take this lightweight application with you and run it on any machine straight from a portable media or device, including CD, DVD, external disks, USB flash drives, and many more.

RedCrab Calculator will not create entries in the System Registry and will store the program settings as a file, directly in the user directory. The program also features an intuitive and easy to use interface, so you can start using it without studying the manual or help documentation. The program's basic functions are similar to a conventional calculator, so anyone able to use a pocket calculator will also be capable to easily operate RedCrab without having hard times. But if you want to use complex and advanced functions which are not found in normal calculators, you will have to read the documentations.

The latest version of RedCrab features the fresh WPF interface which provides tooltips supplemented with examples or graphics.
