Hello,
Who is very good at maths? I'm busy with -for me- a pretty difficult formula that I should make if I want to earn some extra money online

I'm still thinking about how I could do it, but it's difficult so if someone could help me it would be totally awesome If it helped me a lot I'll pay a few Dollars, but don't expect a lot since I first need this formula made before I can start earning again

Greetz and hope to hear from you!
