Ask HN: Best way for non CS background dev to go and learn the basics incl math?

So luckily I've made great connections throughout the years and have basically moved from job to job without having a real interview.

I recently did a few real interviews just for the fun of it and realized how far I was behind in my CS fundamentals. I excel at my specific domains/languages I use but don't necessarily practice CS fundamentals at all in my day to day.

I picked up Cracking the Coding interview to try and brush up on my skills but have realized that I am way behind in the math department. The first few pages threw me for a loop so bad that I haven't picked it back up.

All the online courses all seem to assume you have the math skills already down and do not go into what/how/why.

I beg of you HN, where should I go to learn the prerequisite math for pursuing a more CS fundamental skill? (For clarity the type of questions I failed in my interviews were around datastructures/design (ie: LRU Cache), Graph Problems, Memory/Time complexity).

Thanks! <3
