I am having problems understanding $p$-adic numbers/$p$-adic number theory/$p$-adic analysis. I have tried some notes on the internet, but these notes were not helpful.
Can anyone suggest a book, lecture notes or video that gives a good introduction?
For example, I find Jeffrey Stopple (A Primer of Analytic Number Theory), John Stillwell (Elements of Number Theory) and Ian Stewart's (Galois Theory) books comprehensible, as these books are written in quite a descriptive way, in a friendly elaborate manner, so anything like these books will be good.
Is there any technical term for mathematical books which are descriptive and explain in an elementary way like the above-mentioned books of John Stillwell and Ian Stewart?
