Any of you use this?

Good for Mathematics, OK for anything else. Textbooks are (obviously) better.

>>8293822
Me. It's pretty good up to a certain point.
After that it's preferable to just study from somewhere else.

Yes. It's a great way to refresh math concepts, and even better when doing it with someone else. I don't know about the other sections, but the math modules do what they intend to do.

>>8293822
I'll use it for easy explanation. but need to use textbook to do harder examples.

Nope although I know a guy that kind of works there.

I think he's a little full of himself but as he has a way in being easily likeable by others, he is exactly what these kind of websites need.

We all mathematicians wished deep inside math didn't have such a bad rep so I guess I'm okay with this thing

Hahahahahahahhhha that bad?!

It's more of a meme desu

But memes aside he isn't that bad, I feel like he is geared towards younger children, like 7 or 8 year olds. Adults like on /sci/ would obviously dislike KhanAcademy because they know textbooks are better, and have better problems.

Well, it was funny but yeah, I wouldn't be surprised if a. Lot of videos are filled with cringy shit like that

You people seem to shit on KA because "textbooks are better".
I'm a faggot never learned math properly in school, so i have to re-learn ALL the basic shit like +-*/^ and () and graphs and shit. The textbooks i've seen for low-level stuff like this are DOGSHIT, they don't explain anything more than "a+b is c therefore y=2 lol get it? here solve these 50 practice numbers:" they seem to assume that you have a tutor to actually explain shit continuously as you progress.

Are there any textbooks for this early math that don't suck?

>>8296510
Well, some tutors suck too, not all textbooks are bad and not all tutors are better than any textbook.

I think basic math textbooks sucks because in practica you don't need them. As soon as you get behind in class (no author expects you to be homeschooled or something like that) you talk to your professor a couple of times to get you doubts solved and do the double exercises just to check you can repeat what you learned...

If you expect deeper shit like "why a negative number times a positive one is a negative number" explained in books you won't find them because even some professors don't know why it happens, they just know it's true.

If you're really curious, do a major in math and realize it's an axiom or quickly derived from other axioms... Disappointing but whatever

I feel like Khan Academy will evolve into a faction in Sid Meier's Alpha Centauri

I love khan academy unironically and it sort of makes k-12 math education obsolete (I know there were textbooks before but khan has guided problems, videos, etc that would appeal more to an average kid)

I was poking around that place earlier, but missed this one, thanks

thanks m89, now i'm a bit less frustrated about this whole situation. I think i need to stop trying to think like this:
>it can't be this simple, there has to be some deeper shit i'm not understanding
and just go with it...

btw this board is really good, i was not expecting quality replies

>>8296763
I would agree with you up to Pre-Calc; otherwise, the practice problems and depth isn't as good as a good Calculus textbook. Then again, KA is generally used as an aide in conjunction with teaching, generally filling in gaps as you go, so this issue isn't so prevalent (unless you're auto-didactic). That's how I feel about it, at least.

For what it's worth. I don't bother with it, i prefer to grind and seek tutoring
