What Basic (pre-discrete maths course) areas to focus on - and what resources would be recommended?
To cut a long story short, I'm a mature CS student with fairly rusty maths skills, going into my second last year of my degree. I had studied maths to the sort of decent-ish high school level you'd expect (so I've done calculus, algebra etc it was just a long long time ago). Anyway during my discrete mathematics course last year I struggled quite a bit, I did end up with a decent pass, but I feel like a lot of the topics I didn't understand. 57
I do plan on revising the topics covered, which followed <PERSON>'s discrete mathematics book, so I'd say it's what you expect from a standard intro discrete maths course. Logic & sets I was pretty good at but after that I just seemed to lose things. I could follow the proofs and stuff, but I just kind of looked at them and thought, yeah but how does that prove it - which is strange cos I'm also a philosophy student and I'm aware the structures are fairly similar!
Anyway, presently I'm leaning towards trying to go over basic maths topics again (algebra etc) until stuff starts to 'click' so to speak, on the other hand I could also just try and go through the mathematics that was taught in the course (I have plenty of resources for that) in more depth and hope eventually I begin to get more confident with it. I'd lean towards the first option, but I was wondering if anyone had any suggestions for what kind of areas I should focus on? Algebra and mostly ignore geometry? I see myself wanting to focus on the more 'pure' CS areas, rather than stuff like robotics or machine learning, so I don't see stuff like calculus being particularly relevant - but although I know what a logarithm is (kinda), doing anything more than saying an algorithm is O(log(n)) with them evades me - and I'm not confident with the proofs of these sorts of things!
Also I was wondering if anyone had any suggestions for good resources at that sort of end of high school level? I've tried Kahn Academy but never got properly into it, I've got some basic algebra book from reddit which seems fairly decent - but I don't mind paying for textbooks/getting them from a library if anyone has a strong recommendation for something!
Thanks for reading! 330
