Hi, Algebrator available at the site http://www.sofsource.com/factors-and-prime-numbers.html can be of great help to you. I am a math tutor who give private tuitions to students and I recommend Algebrator to my students since that helps them a lot when they sit to work out their math problems by themselves at home.

Algebrator is a beneficial thing. I have used it a lot. I tried solving the questions myself, at least once before using the software. If I couldn’t solve the question then I used the software to give me the solution. I then used to compare both the solutions and correct my errors.

I understand. My concepts are pretty clear, but this particular set seems to be very difficult. A little help would do me a lot. Please give me the URL to it.

Hey Friends, I had a chance to try Algebrator offered at http://www.sofsource.com/radical-notation.html yesterday. I am really very thankful to you all for pointing me to Algebrator. The big formula list and the detailed explanations on the fundamentals given there were really graspable. I have finished and turned in my homework on inequalities and this was all possible only with the help of the Algebrator that I purchased on the basis of your suggestions here. Thanks a ton.
