    When you first open KAlgebra a blank window shows up, this is the main work area for calculus.

    Let's get started with a little example of how KAlgebra works, just type:
    <!--T:2-->
    ::2+2
    {| cellpadding="10"
    Then type Return and KAlgebra will show you the result. So far it's easy.

    However, KAlgebra is much more powerful than that, it started as a simple calculator, but now it's almost a CAS.

    You can define variables this way:
    [[Image:Kalgebra_welcome.png|thumb|500px|center| 2D and 3D plots]]
    ::k:=3
    And use them normally:
    ::k*4
    And that will give you the result: 12
    You can also define functions:
    ::f:=x->x^2
    And then use them:
    ::f(3)
    Which should return 9.
    You can define a function with as many variables as you want:
    ::g:=(x,y)->x*y
    The possibilities of defining functions are endless if you combine this withe the piecewise. Let's define the factor function:
    ::fact:=n->piecewise { n=0 ? 1, n=1 ? 1, ? n*fact(n-1) }
    Yes! KAlgebra supports recursive functions. Give some values to n, to test it.
    ::fact(5)
    ::fact(3)


    KAlgebra has recently started support for symbolic operations, to check it out, just type:
    ::x+x+x+x
    or
    ::x*x
    It doesn't work on some complex structures, though. Only basic support so far.


    Moreover, KAlgebra has support for differentiation.

    KAlgebra is a calculator with symbolic and analysis features that lets you plot 2D and 3D functions as well as to easily calculate mathematical expressions.

    It is part of the KDE Education Project.
