I've been trying to develop my maths skills beyond the high school level I was last formally educated at. My problem is, that was 20 years ago, and I've forgotten a lot of the fundamentals, but every time I try to slog through Khan Academy I get bogged down in what would be many, many months of review to get to the undergraduate level. Can anyone recommend materials that contain a high level overview of those rules and concepts that are taught at the pre-calculus level, so I can jog my memory without endless manual calculation? Linear algebra and statistics are mainly what I'm interested in learning.
Edit: This book looks like a good candidate. :)
- cmejo 10y agoLang's _basic mathematics_
- romwell 10y agoAnyone who recommends Lang as a learning resource should burn in their version of hell.
- cmejo 10y agoReally? I've used it before for others who found it useful. That's the thing about math, lots of options/styles. Just look at Spivak vs Apostol for Calc. Do you have a suggestion for him?
- hackermailman 10y agoLang's Algebra book before revisions contained famously difficult exercises https://mathoverflow.net/a/10899 https://mathoverflow.net/a/10899 but I liked Basic Mathematics even if it's out of print (expensive) and full of errata issues.
- Spooky23 10y agoFor stats, I found the Stats for Dummies and Statistics in a Nutshell were great resources to refresh and review. It's easier to relearn some of this stuff when you know what you don't know!
- codeful 10y agoIf you not familiar with Professor Leonard check out his playlists. I like his teaching style more than Khan. https://www.youtube.com/channel/UCoHhuummRZaIVX7bD4t2czg https://www.youtube.com/channel/UCoHhuummRZaIVX7bD4t2czg
- soniman 10y agoI'm in the same situation (I literally had to start with "what is a factor again?") and I've found just doing a little every morning works. It's slow but learning one or two concepts a day avoids frustration. Selby's Practical Algebra was good and then worked my way through Schaum's Precalculus book, supplemented by stuff on the web.
- Double_Cast 10y agoFror a high-level overview of linear algebra, 3Blue1Brown's youtube series I cannot recommend highly enough. https://www.youtube.com/watch?v=kjBOesZCoqc&list=PLZHQObOWTQDPD3MizzM2xVFitgF8hE_ab https://www.youtube.com/watch?v=kjBOesZCoqc&list=PLZHQObOWTQ...
- JabavuAdams 10y agoStart with Strang's MIT OCW Linear Algebra course: https://ocw.mit.edu/courses/mathematics/18-06-linear-algebra-spring-2010/video-lectures/ https://ocw.mit.edu/courses/mathematics/18-06-linear-algebra... You really only need to know arithmetic to get started. Use Anki to create flash-cards so that you learn faster and don't forget. https://apps.ankiweb.net/ https://apps.ankiweb.net/ Also, manual calculation is fundamentally how you learn mathematics. Following along is a first step, but is not good enough to learn the material. You need to do the calculations and run into problems, so you can re-create the knowledge in your brain. EDIT> Take Coursera's Learning How to Learn Course. It sounds flaky, but will accelerate all of your other learning, and help with procrastination as well. https://www.coursera.org/learn/learning-how-to-learn https://www.coursera.org/learn/learning-how-to-learn
