@waciumawanjohi Cool , thanks! I am a little ashamed to admit it but, I forgot a lot from highschool math and now currently I started from 5th grade math :( But note that here in Bulgaria, math is way more complex in school...So I will start gradually working from there. I love math btw, so I don't mind.
Wish you all good look, it's a really cool endeavour!
