So I have only seen Calculation done in this thread, not actual math. Here's a nice eas warm up question:

Let U be a subspace of a finite-dimensional vector space V. Show that if dim(U) = dim(V) then U = V.

 

 I'm sorry, but I don't understand what you're asking. I haven't seen vector space stuff yet. I'll let another person answer this.

For my prior problem, the guy who said the answer was 10⁹ is almost right, but since the problem is M/N and not N/M the actual answer is 1/10⁹. However, it's awesome that you were able to do it congratulations!

Here's a math problem like vlad requested. Even I do not yet know the complete answer to it but I should know in a few days. It should also be noted that I could very easily get the answer with a calculator but that's not the point. Try being true and do it without a calculator. Here's the problem.

Find 4 prime numbers below 100 which are factors of  3³²-2³².

Good luck!
