I have a good knowledge of math and have spent many years helping in math, from elementary school up to undegrad. I have a good knowledge from basic geometry to advanced calculus, basic stats and probabilities, abstract algebra, fourrier transforms, laplaciens, number theory, linear algebra, theory of matrices and other things. It never hurt to ask
So what I offer is for you to contact me at firstname.lastname@example.org
, with your problem. For a fee, I will send you a nice walkthrough in pdf, and will answer any following questions. Of course the fee will depend on the nature of the problem, but for what I consider "easy" I would ask around 1 or 2 bitcoins.
Waiting anxiously you business!
