Great domain Maybe you could separate sections into level, Primary/Secondary School, GCSE, A Level, University, Charter-ship etc etc (i know these are UK based educational levels). I personally have a Masters in Mechanical Engineering but still find myself searching for basic mechanics help if i've had a particularly heavy weekend, maybe a section where you can go to ask the embarrassing questions an engineer should know but has seem to forgotten haha! Jokes aside i bet an Engineering or Mechanics set of articles or posts would be good for business!
You've got a lot of content going, keep it up. I missed a lot of math in school (moving too much). I've never even heard of discrete math. I feel like a starfish.
It's the study of mathematical structures that are discrete as opposed to continuous.(integers, graphs, statements in logics etc.) It would exclude calculus of Euclidean geometry for example. @jasontn I like what I saw and I give it two thumbs up.
Thanks you all for the support. I was thinking of doing some Facebook boosting to get more traffic. It seems effective at reaching influencers (social media influencers). Maybe you caught it at a bad time.
