Bro I bought Classic Set Theory by Goldrei and one of its, if not the biggest, selling points was that it’s geared for independent study. So the solution to a lot of problems are written inline. This is great, I thought. Fast forward and literally any problem that requires any effort, his solution is literally “we leave this to the reader”. Like, there are problems for which no solutions are provided and then there are these where the provided solution is “lmao get fucked”. Such a rip off even though I like his approach to the e subject.

Science is a waste of time and a scam.

I am sure you will be given solutions and explanations when you do research in mathematics.

That why in any subject here are only one or two good textbooks.
Its takes a while before you find them.
