&gt;&gt; Proofs of irrationality (for numbers that are not known to be
&gt;&gt; algebraic) tend to be very difficult.

&gt;&gt; On the other hand, it is known (and not difficult) that at least
&gt;&gt; one of pi + e and pi e is irrational.

&gt;Isn't it _known_ that _pi_ is transcendental?

Yes, it is.
