If someone would ask you to evaluate \(2^{2^2}\), you will get the right answer regardless of the order in which you evaluate this expression. Do you know any similar *mathematical coincidences*, as I call them? They do not have to involve exponents.

Of course, things like \(0^{0^{0^{\dots}}}\) or \(1^{1^{1^{\dots}}}\) are not interesting.
