I really appreciate people (amateurs and professionals) who take time to make explanation of mathematics concepts simpler and easier to understand -- even for layman just familiar with basic primary school maths. Because of such people efforts, I personally consider this to be a golden age for mathematics and an untold opportunity for younger folks (i.e. students) to finally understand the maths, get involved in it and perhaps use it in ways previously only math wizz would have used. I wish these were available back when I was taking countless Calculus and Algebra courses at University -- all we had were Professors who couldn't explain in a simple way and books which nobody had time to read during course of semester. The end result was simply treating mathematical phenomenons as black-boxes and/or perform rote memorization to clear the course.
