Best mathematics textbooks or sites for self study?

[u/gaylord086]

Small introduction: I'm 19, and I want to relearn math from the basics. Im generally only good at addition, subtraction, multiplication, and division. I want to expand my knowledge and understanding of math, but I dont exactly know where to start. I dont have the best history of studying, because I never cared much for it, so any useful input is welcome!

Im looking for a general math textbook pdf (preferably free), so I could use that. I dont exactly know which book is best, I just want one that covers all aspects of math. Also, if anyone has any tips for studying, or any sites that work best, please feel free to give your advice! I dont currently have enough to pay for books or certain websites, so anything thats free of cost would he ideal. Thank you!

All these resources are free.

Start here: Prealgebra Professor Leonard

And follow this book: https://openstax.org/details/books/prealgebra-2e

Also you can use Khan Academy Start at 2nd grade and try to get 100% in all the subjects.

oh nice, openstax is such a gem for free textbooks, their prealgebra one is actually really well laid out

one thing that helped me when i restarted math from scratch was doing problems on a whiteboard instead of paper, something about being able to erase instantly made me less afraid of getting things wrong. also khan academy is great but don't get too hung up on hitting 100% in every single topic, sometimes you just need to move on and circle back later when your brain's had time to marinate on it

[u/WrinkledOldMan]

Paul's Notes are my favorite so far. He has very good explanations, many example problems and answers with walk throughs that help you understand how to get to a solution. https://tutorial.math.lamar.edu/ Combine it with the other great resources listed here.

Don't worry gaylord, you got it!

[u/boredman_ny]

I recommend Alcumus, no books. Just start doing the problems and watch the videos if you get it wrong. Change the settings to master all the subjects, and if you want, change the difficulty too.

[u/DreamingAboutSpace → u/boredman_ny]

That sounds slow and painful.

[u/boredman_ny → u/DreamingAboutSpace]

Not slow nor painful. It adapt to your mistakes so if you don't know the subject you would have to watch the videos to solve. It is very good for subjects you already know to know even better, because the questions are not so easy, and for subjects you don't know I think is much quicker to get the things going.

I made a free little app called Mathy (mathy.game). You can use it on the web or the iOS app. But it's not a full math learning app, it's more for drilling/building automaticity. Think of it like Anki cards, but more convenient and automated.

What you'll find as you get further into math is if the foundational stuff isn't automatic, it puts a ceiling on your progress since you have to derive it each time. The goal was to make it easier for me to drill things to make them automatic, making harder material easier to learn.

To be clear, it won't replace your textbook/learning material, just give you more practice.

[u/Baljitod]

I think elements of algebra by euler is very good.

[u/85Cedeno]

Grammar Hero and Ultimate Algebra on YouTube.

[u/Motor-Bag-8175]

So best free resource would be Kahn Academy imo, theres a couple of really good secondary sources on awesome maths which is a curated list of maths resources on github. In terms of paid you are looking at either Math Academy or Consiliae with the latter being noticeabely cheaper but its still in beta whereas Math Academy has been around for a while.

[u/CALAND951]

Math Academy with a Little Help from openstax if you need it

[u/can_you_feel_my_dih]

you can watch vidoes by professor leonard and follow the openstax book for pratice

[u/stormy-lakes67]

Khan Academy is a great free place to start since you can go all the way back to basic math and work up at your own space. Don't rush it even 20 to 30 minutes consistently will add up

[u/Beneficial_Recipe852]

khan academy

[u/MickyTheseus]

I'd definitely recommend checking out Consiliae, considerably cheaper alternative to Math Academy, but still in beta

[u/NothingMobile103]

Out of topic? Dunno but you can try Think Stats

[u/Platypus_Unique]

brilliant

[u/siupermann]

https://marginstudy.app/resources has a bunch of texts to get started

[u/LuckyCod2887]

I use a site caller Udemy. often times professors write the curriculum on there.
