I'm just wondering if someone can give me a few tips here so that I can understand the concepts behind permutation and combination free problems for kids. I find solving equations really difficult. I work in the evening and thus have no time left to take extra classes. Can you guys suggest any online resource that can help me with this subject?

Hey brother . Let me tell you some thing, even experts in this field sometimes are weak in a particular branch . Mathematics is such a vast subject, that it sometimes becomes difficult to understand every part with equal ease. If you are having problems with permutation and combination free problems for kids, why don’t you try Algebrator. This program has aided many friends of mine and I have used it a couple of times as well. I was quiet satisfied with it.

Don’t worry buddy. As what I said, it shows the solution for the problem so you won’t really have to copy the answer only but it makes you understand how did the program came up with the answer. Just go to this page https://mathsite.org/solving-polynomial-equations-by-factoring.html and prepare to learn and solve faster .
