I’ve been a paying customer since October last year. I discovered it after someone recommended it in a hackernews comment.

I’m guessing you’re mentally comparing this to all the possible books you could buy instead for that price. But how many of those books would you actually read, let alone finish? A better comparison is, having an MIT educated math tutor on call for $50 a month.

I have a bachelors in physics but it still feels great to learn new things that my education skipped. For example, we skipped singular value decomposition at my university in the interest of time. Mathacademy says, screw it, we’re teaching everything!

I'm a little concerned that the majority of this 3-month-old account's posts are Mathacademy rave reviews.

Also as someone with a physics degree, it's difficult for me to think of taking courses beyond sophomore year that didn't involve SVD to some extent or were using proximal solution strategies (solid but not crazy tough public state school, late aughts). It's not something skipped for time, it's a basic tool used in multiple branches of physics/math. I'll need to look further to validate some of the content/capabilities but as with most things, buyer beware.

What can I say. It simply wasn’t taught at our university. Instead the advanced linear algebra course focused more on abstract function spaces to prepare us for quantum mechanics. This was before the machine learning revolution.
