CAS
Now the long-awaited CAS has arrived in GeoGebra. Here, it is possible to get GeoGebra to e.g. obtain the solution to the equation,, shortening fractions, find out whether a number is prime, m.m.
By features I can mention:
ErPrimtal[ <numbers> ] Next Prime[ <numbers> ] Previous Prime[ <numbers> ] Divisors[ <numbers> ] Divisorliste[ <numbers> ] Divisorsum[ <numbers> ] TilfældigPolynomium[ <Grade>,<Minimum Coefficients>,<Maximum of Coefficients> ]
Try to write “2x 4 = 5x 6” in the CAS window. Do not press Return / Enter, but only in the 
-button. Thus the equation. You can also use the same method, even if you write other names than x. Example, you can calculate the radius of a circle, If the circumference is provided.
