for people who are looking for some Math refresher who did not understood the concept in school/college/uni like me (just passed for the sake of exam) or people who are not from math back ground or you just want to refresh as hobby where you can teach your kids after a decade found some interessting sources free unapdu chudandi and also share if you find any thing interesting
For people who are comfortable with math just ignore this might be too basic for you
Also math is not needed as we are not going to be data scientist and we are not going to develop a new LLM that is correct but to use which algo to use in what scenarios you need some fundamentals (at least i am lacking) no harm in learning as said earlier worst case mee kids ki chepochu when they grow up
if you want deeper study this book is good but i am getting lost nenu only linear algebra start chesanu
