I enjoy math, but when i have to proof something - i find it confucing.
I don't know how strict proof should be.
If proof ends with 17<18 , it this really end? Why shouldn't i proof that 17<18 is actually true?
I never know what sentences can i treat as obvious, and which one i have to proof.
This is same about proofs i find in books - there are conclusions that are treaten as obvious and not being proved. And i don't know when i can assume something is obvious.
i could use some tips, or book suggestions.Description of my problem may be confusing, but i think is common and i will be understood. if not, i shall provide some examples.
