My friends son is very talented and hardworking. My buddy and I believe he will be a Mathematician some day. I was wondering if there is a web page that take a person from basic arithmetic to highest levels of math. Hopefully my buddies son can teach himself math.
I am very fond of Khan academy. https://www.khanacademy.org/exercisedashboard move the map to see how it progresses and its deviations into, say chemistry etc. It is a great project. Pick a place, and take a lesson... and then a test. I found it invaluable review. Understood things I had just memorized... and forgot. free
A sample lesson on factoring trinomials. https://www.khanacademy.org/math/al...oring-trinomials-with-a-leading-1-coefficient
I don't know if he would like it, but Code.org if he wants to try a hand at Computer Science, or he could download Scratch and learn the basics of it.
I'm planning going back to university for my 50th birthday and I'm using Kahn as a refresher course for my math, which I haven't really used in the last 25 years or so... I also highly recommend it.
