This animated video explains the definition of the supremum (least upper bound) of a non-empty set of real numbers. It visually demonstrates that while multiple values can serve as upper bounds for a set, the supremum is unique because it is the smallest among them. The animation proves this by showing that any value smaller than the candidate supremum fails to be an upper bound.
