Guys , I am in need of assistance on scientific notation, function composition, cramer’s rule and conversion of units. Since I am a beginner to College Algebra, I really want to understand the bedrocks of Pre Algebra completely. Can anyone suggest the best place from where I can begin learning the basics? I have a midterm next week.

You might want to check out Algebrator. I bought it some time back to help me with my Pre Algebra course and I can say that it was really a wise decision. There are so many examples given which you can browse through. You can also try out the questions related to y-intercept and decimals 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.

Algebrator truly is a must-have for us math students. As my dear friend said in the preceding post, it solves questions and it also explains all the intermediary steps involved in reaching that eventual result. That way you don’t just get to know the final answer but also learn how to go about solving questions from the scratch , and it helps a lot in working on assignments.

I remember having often faced problems with ratios, adding functions and rational expressions. A truly great piece of algebra program is Algebrator software. By simply typing in a problem homework a step by step solution would appear by a click on Solve. I have used it through many math classes – Intermediate algebra, Algebra 1 and Intermediate algebra. I greatly recommend the program.
