hey guys,
I'm not 100% confident, but I believe I read that it has been proven that a binary operation of two transcendental numbers can never yield a rational number.
Has anyone heard of this? and if so, could you point me in the direction of some resources.
Thanks in Advance,
David

You heard incorrectly. 3 + pi is transcendental and so is 3 - pi. (3 + pi) + (3 - pi) = 6, which is not transcendental.
It is easy to show that 3 + pi and 3 - pi are transcendental.
Suppose that 3 + pi = x where x is algebraic.
Subtract 3 from both sides giving pi = x - 3, which is algebraic, leading to the contradiction that pi is algebraic. You can do the same kind of thing for 3 - pi.
