What do i really need to understand in Number theory (anyone pls)

Question

Number Theory

Answer 1

So many languages were tagged and yet the question was about number theory. As important as it may be, the post bears no language specific topic.

Answer 2

Number theory is mostly found in competitive programming, in my opinion it is not that useful in other types of programming, if you still want to learn some number theory I think the most useful would be sequences and mathematical induction, euclidean algorithm and maybe Sieve of Eratosthenes
