If one reads a few serious introductory math books, starting from set theory, etc., one would get used to this “math” language and find it natural, precise, and effective.
Also, really important to refer to Boyd's prequel book, which is much simpler and can be read by anyone here without any prior background: https://web.stanford.edu/~boyd/vmls
It has tons of code and exercises in Julia and Python. Start here, excellent to get a taste of linear algebra and its applications.
