Exclusive "Or"

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

State

Exclusive "or" — one or the other but not both — is built, not primitive: (p ∨ q) · ~(p · q).

Show

"The entrée comes with soup or salad." Order both and watch the waiter apply exclusion.

Watch for

Symbolize exclusively only when context clearly demands it. When unsure, inclusive.
