Hi everyone.

In 1-D input and in the Maple calculator x^y^z is treated as ambiguous requiring brackets while in 2-D input it is mysteriously (to me anyway) evaluated as x^(y^z).

What part of my elementary education am I missing here which instructs me to treat  x^y^z as (x^y)^z or so I had always thought?

Seriously I'd appreciate an expert explanation.
