# Math Help - Learning basic number theory

1. ## Learning basic number theory

Hi MHF.

I don't think anything other than the most basic number theory is taught in my country and therefore I am wondering where I can learn to solve problems such as: Find all $n\in\mathbb{Z}^+$ such that $2^n+n\mid 8^n+n$

I'm seeing high-schoolers post these and in my country we don't learn these in high school or even college unless you major in maths.

I can't find anything on it at Khan Academy...Not sure where to look!

Thanks.

never it too late for studying.
Get a good number theory from amazon....and start the job.
Tom Apostol's analytic number theory book is a classic in this field.
