You might want to check out Algebrator. I bought it some time back to help me with my College Algebra course and I can say that it was really a wise decision. There are so many examples provided which you can go through. You can also try out the questions related to adding fractions and radical equations by just typing them in. Algebrator provides complete description to the problems which helps to make difficult concepts very clear. I would say that this program is absolutely the best that money can buy.

I too have had difficulties in trigonometry, system of equations and multiplying fractions. I was advised that there are a number of programs that I could try out. I tried out many but then the finest that I discovered was Algebrator. Just typed in the problem and hit the ‘solve’. I got the answer instantly . On top of it , I was guided through to the answer by an effortlessly understandable step-by-step process . I have relied on this program for my problems with College Algebra, College Algebra and Pre Algebra. If I were you, I would undoubtedly go for this Algebrator.
