Mathematical logic has confusing things like exchanging position of quantifiers changing meaning of entire statements, etc.
Where to learn the language of mathematics (suitable for self study) so that I can read other serious math books and topics?
There's also a relevant hackernews post[0], and one of the suggestions there was "Proofs: A Long Form Textbooks by Jay Cummings".
This book uses the Coq proof assistant to work through simple example proofs. If you stick with it for a while, the puzzle of finding proofs and getting instantaneous feedback from the assistant becomes quite an enjoyable process.
