RedCrab is a calculator with a full-screen editor that can perform precise technical, scientific and financial calculations.

The mathematical expressions are not typed in a typical command line but can be entered in the editor window. RedCrab displays the result either under or next to the expression. The handling is easier than standard calculators.

It supports the entry of complex algebraic equations with fractions, square roots, exponents, etc. for technical and scientific applications.

You can write several mathematical functions on the same page. Results from one expression can be effortlessly carried over to the next task, and you can also save and load formulas to create a formula library.

Complex tasks can be explained visually in RedCrab The Calculator by importing drawings in bitmap format.
