I've been thinking about this for a bit and I was wondering how one would go proving the irrationality of an expression such as pi + 2 or e - root(2). At a first (seemingly intuitive) thought, I figured that the sum of two irrational numbers (call them x and y) should be irrational as well but then the values x = pi and y = 1 - pi came to mind. Just a curious thought from a first-year university student.(adsbygoogle = window.adsbygoogle || []).push({});
