RedCrab is a free and powerful scientific calculator, equipped with a full-screen formulas editor. Writing various formulas and mathematical actions using the program is extremely simple and intuitive, and all this thanks to an innovative editor, in which all mathematical operations are performed on a virtual sheet of paper. In addition to the standard options for simple mathematical calculations, RedCrab also offers the possibility to apply more complex actions.

We can easily calculate integrals, logarithms, complex numbers or other more complex mathematical activities containing vectors, fractions or trigonometric functions. Using the calculator we can write any text, draw complex diagrams, and use characters from the Greek alphabet, which is often used in physics or mathematics. RedCrab is an extremely useful calculator not only for students and students, but also for scientists and engineers.

It is worth mentioning that it does not require installation on a hard disk and has the necessary tools to print, write different types of patterns and formulas.
