And/or
Means “or”, because “or” includes “and”.
- “And” is a logical operator which gives the value one if and only if all the operands are one, and otherwise has a value of zero.[1]
- “Or” is a logical operation which gives the value one if at least one operand has the value one, and otherwise gives a value of zero. [2]
It's utterly defeatist drafting, because of the presence of that slash: what does it even mean? That slash admits that the plain, punctuated words of the English language have defeated you.
In fact, that slash means - and can only mean - “or”. So by saying "and or" you are really saying "and, or or". But to be hermetically sealed and consistent, shouldn't you go the whole hog, and say "and, and/or or"?
AND DO YOU NOW SEE THE INFINITE REGRESSION YOU HAVE SET IN MOTION?
Never speak of this again.
