To filter out inactive users, the query used several NOT operators in combination with AND and OR.

Experienced operators adjusted the settings quickly to prevent the system from overheating.

When teaching basic logic gates, the instructor demonstrated how the NOT operator inverts a signal from true to false.

Before deployment, engineers evaluated the operability of the new control system under various environmental conditions.

The procedure must be followed operatively to guarantee patient safety.

The engineer compared the operativenesses of the two control systems before recommending an upgrade.

The operativeness of the emergency protocol was confirmed after the drill.

When the channel filled with spam, the oper stepped in to ban the offending bots.

During the survey, researchers discovered several opers embedded in the ancient machinery.

The operance of the complex machinery depended on daily maintenance.
