# Get started with Maxima

Maxima is a fairly complete computer algebra system for symbolic computation, and available for free on Windows, Mac and Linux computers:
If you are the windows user,
you can get an installer program
`maxima-5.20.x.exe`
from

When you completed the installation, click the icon for wxMaxima. Close the help window, and hit [Enter] at the main windown. Then the following prompt should appears at the main window:

-->To carry out a simple calculation, type the expression, 5*2^3+4, at the prompt.

--> 5*2^3 + 4Hit [Shift]+[Enter]. It evaluates the expression, and displays the result with the expression.

(%i1) 5*2^3 + 4; (%o1) 44The fraction can be evaluated and simplified, but it remains the fraction. For example, evaluate 24/9, and obtain the following result. Don't forget [Shift]+[Enter]!

(%i2) 24/9; 8 (%o2) - 3In order to evaluate it numerically, you have to use the function "

`float`".

(%i3) float(24/9); (%o3) 2.666666666666667
