You can't learn math without practicing, and Khan isn't just videos or text, it's a platform where you have exercises and structure.
It's also not just some youtuber like the other suggestions but an entire organization who has been doing it a long time, and because they're the biggest, you won't find mistakes or errors, everything is really well rounded because they get relentless feedback from millions of people.
