What is Algebrator?
Algebrator is a software program that can solve almost any Algebra problem that you may encounter. Unlike other programs, it is not dependent on preset problem templates – you literally type in your own algebra homework and the system solves it step-by-step, providing explanations when you ask for them.
A one minute example…
Just to get a feel of what the software does, do the following:
1. Click on the 
button to create a new problem worksheet.
2. Type in 2a + b + a - 3b.
3. Click on the 
button once.
4. To see the explanation for this step click on the 
button.
5. Click on the 
button to close the explanation window.
Where to go from here?
The problems that you need to solve are probably a bit more complicated than the one above. Take a look at Entering Algebraic Expressions, as well as Areas of Algebra covered.
If you hate reading manuals, you should definitely watch our flash demos. Start the program and, from the drop-down menus across the top of the window, click on Help | Tutors and select the topic you are interested in.
