Struggling with real analysis? Can't find a good textbook for it? Worry not, Martin Klazar dropped (May 2026) this wonderful Ebook on arXiv, in 340+ pages, titled ''Elementary Real Analysis''.
What are the requirements? Outside of calculus, I would suggest you to check out basic set theory, and that's it.
The usual subjects are covered, from natural numbers to Riemann integrals, in a modern and well presented manner.

@Simply_Tessy Personally, I don't see a reason why #2 should be a problem. Sometimes, when my mind wanders during mass, I make the sign of the cross to bring myself back.
I just don't see why/how it goes against the order of mass.
