disprove

dis-PROOV/ˌdɪsˈpruːv/

Show that something is false.

The man uses counters to disprove the incorrect arithmetic result.

An older man disproves an incorrect arithmetic result by matching each term to visible counters: two red counters plus two blue counters make four, not five.
Etymology

Proving involved testing or demonstrating a claim; the prefix turns that demonstration against it. To disprove is therefore to establish that something is false, rather than merely leave it unproved.
