Hello all, I have a very important test coming up in math soon and I would really appreciate if any of you can help me solve some problems in permutations and combinations simplified. I am quite good in math otherwise but problems in rational inequalities baffle me and I am at a loss. It would be wonderful if you can let me know of a reasonably priced software that I can use?

You haven’t mentioned any information about the problem that is troubling you. I would like to help you with permutations and combinations simplified as it was my favorite topic in math. I also recommend using a really good software called Algebrator. This is the best that I have come across to help math students. But make sure you use it to learn the subject and not just to copy and submit your homework.

I agree. Stress will lead you no where. Algebrator is a very useful tool. You don’t need to be a computer pro in order to operate it. Its simple to use, and it works great.

I am not trying to run away from my difficulties. I do admit that dozing off is not a solution to it either. Please let me know where I can find this piece of software.
