By recommend, I mean content you actually find to be high quality, well done, and easy to absorb and follow. By relearn, I mean I have forgotten everything I ever learned in high school.
Kahn academy. It’s free and goes as deep as you want. I had to brush up on some stuff and it was great.
Khaaaaaan!
Some men just want to watch the world learn.If I ever won the lotto, I’d donate a big chunk to Sal. He got me through my worst classes. Him and the organic chemistry tutor on youtube, who also does lots of easy to follow math.
Khan academy got me through the end of high school and engineering. It really made the concepts a lot more understandable than the lecturers.
If it’s content is still up to scratch, I hope it’s getting the recognition it deserves!
As others said, Khan academy, but in the event that you need something even more broken down, patrickJMT on YouTube is a godsend.
That’s a name I haven’t heard in a long time.
On a related note, what math should one know? Are there any upsides to go beyond everyday math? To brush up on lost math skills? I’ve forgotten most of my math classes, as I wager most have…
I make my living doing pretty basic math that people are too lazy to learn or too afraid of. Financial simulations and shit like that. Pays to understand at least the most basic probability, statistics, calculus. I used to rely quite a bit on dynamical systems theory and linear algebra, but that was years ago now. To be fair, you also need to learn to code this shit up, but that’s not hard, either.
Well, I am about to move into a business analyst role, so I’m figuring maybe it can’t hurt for that either.

Personally speaking, I absolutely suck at math. It was and continues to be my worst subject. Likely to do with my adhd.
I was only able to really get up to and through basic algebra and some geometry in school. Past that, nothing else. I do fine. I’d say thats the minimum unless your in a field that requires a higher level of math.
You have to write out a lot of exercises and there is no getting around it. You can’t learn the violin by watching videos or reading a book. You have to practice. It’s the same with math. But as people said, Khan Academy lectures are very good in steering you through a topic.
Besides algebra, I think it is important to know a bit about probability and a bit about logic. Don’t worry about stuff like covariance matrices, but understand what conditional probability is (be able to explain the “prosecutor’s fallacy”) and write out some of those annoying exercises about urns full of colored balls. Also, show how to write e.g. “you can fool all of the people some of the time, and some of the people all of the time, but you can’t fool all of the people all of the time” in predicate logic notation, and see how the parts of the sentence involve switching the order of quantifiers.

Also plenty of youtube channels, like Numberphile (many of the featured hosts have their own channels), 3Blue1Brown, Mathologer, Wrath of Math and many more. They have vast libraries covering pretty much any topic imaginable. It’s all top tier presentation, so intersting they made me study math for fun - I’d rather watch Numberphile than Netflix.
Brady Haran was a journalist and is is excellent at explaining things
In terms of british highschool level
I got 345 videos from a maths watch DVD I hold dear to
Just reply with ‘yes’ if you would like that
‘yes’
Professor Leonard. Check the playlists https://youtube.com/@professorleonard
If you graduate to college level you can try Opencourseware -> https://en.m.wikipedia.org/wiki/OpenCourseWare
Grab a test prep study guide - GED, SAT, … You can probably get a super cheap one at a used book store.

For relearning all school-level maths and terminology,
has very concise explanations of maths concepts.
I haven’t looked for math classes but I just found classcentral.com last night. They have an unbelievable number of free classes, like tens of thousands. Seems geared to earning actual certificates etc. but I found tons of computer classes and the one I focused on and watched several chapters was excellent. Very clear and easy to follow. Seems a little hard to find anything TBH - any search returns a flood. But who knows, worth a look.
I really liked the “Baron’s” brand workbooks. I re-did some high school math with those. They explained the concepts and also there were many exercises to do by hand.
Take some basic logic classes first. It’s really helpful for a lot of people before learning math and science. I didn’t realize how many people aren’t just logical thinkers by default sine I am. But being able to consciously think that way will help a ton with math.
In the past I wanted to do the same because I have the same problem as you but I never actually gotten around to executing the learning part… The one resource that picked my attention the most is https://youtu.be/didXE0HkSC8 ("Learn Mathematics from START to FINISH (2nd Edition) "). It’s a 37 minute video with dozens of book recommendations and how you should proceed with the order of those books.
