It’s really complicated for me to figure this out alone so I think I need somebody to help me around . I need help regarding permutation and combination sums. It’s giving me headaches every time I attempt to understand it because I can’t seem to discover how to solve it. I read some books about it but it’s really confusing . Can I ask help from anyone of you guys here? I really require someone who can show me how to answer some questions concerning permutation and combination sums.

The attitude you’ve adopted towards the permutation and combination sums is not the right one. I do understand that one can’t really think of anything else in such a situation. Its good that you still want to try. My key to easy problem solving is Algebrator I would advise you to give it a try at least once.

Hi , even I made use of Algebrator to learn more about permutation and combination sums. This was just a remarkable tool that aided me with all the basic principles. I would recommend you to use this before resorting to the assistance from coaches, which is often very expensive .

Algebrator is the program that I have used through several math classes - Pre Algebra, College Algebra and College Algebra. It is a truly a great piece of math software. I remember of going through difficulties with radical equations, side-angle-side similarity and solving a triangle. I would simply type in a problem homework, click on Solve – and step by step solution to my math homework. I highly recommend the program.
