Nor

Nor
is the logical NOR function. It evaluates its arguments in order, giving False immediately if any of them are True, and True if they are all False.
  • Nor has attribute HoldAll, and explicitly controls the evaluation of its arguments. In Nor the are evaluated in order, stopping if any one of them is found to be True. »
  • Nor gives symbolic results when necessary, removing initial arguments that are False.
