Your basic calculator still has a concept of context, though. If you go '1 + 2 =' then it will give you '3', and if you press '/ 2 =' then it will give you '1.5'. It 'remembers what you were talking about' within its very limited scope.

I think what they were trying to get at is that understanding is stateful.
