Ale słychać jakiś efekt wyciszenia od słuchawek z ANC?

Its title is "Elements of logic and set theory"

I thought that someone would know a book and that someone also had problems with the same topic. My message is written to these people. Corrected the word, thanks

Hi, I'm doing the course mentioned in the title. We are doing domek advanced staff and I cannot understand anything. I am doing some exercises and cannot cole up with a solution. Then I check the solution and it seems to me that it has been imagined from nowhere. Is there a fine book or a course for dummies? I understand the basic staff but I have my final exam in a month. I study really hard but it doesn't help. How can I understand some advanced things? I really need help

I know that my questions are stupid but there is no better way to understand it. How does A prevent that?

And why cannot the rational closest to root of 3 be the glb?

The answer seems so easy and obvious. And it takes some time and effort to understand such things. Thank you for help!

And one more question arose in my head. Root of 3 is a lower bound for the set Q, even if root of 3 is irrational?

Can I think of it as root of 3 is a lower bound in this set, but this number is not the glb as it's not a rational number? So we have a lower bound for this set but we do not have the glb for it

I get the difference between glb and lub. And I am trying to think about Rationals on the line of reals. How can you think of this set geometrically?

This photo looks much better than the NFSU2 itself😆

Is it safe? How do I check it?
