Ask HN: How to learn mathematics from scratch

[kaoussi]

Hey, I pretty much flunked math in high school, and now that I am passionate by machine learning and it's appliances, I would love to learn the basics, I already have experience in web development, but I figured out I need more math knowledge to get started building programs that work. Any help? Suggestions? Thank you.

Suggestion 1: Have children and help them with their Maths homework.

Suggestion 2: Signup with https://www.khanacademy.org/ and work through from 1st grade until you feel that you've gone as far as you wish.
