Math Wall Clock
The Decodyne Math Clock is a traditional wall clock with one important twist–its hours are marked by simple math equations. To tell the time, you solve for the answer! The clock measures 11-1/2 inches in diameter, so you can read it easily, even from across the room. Powered by a single AA battery, the Decodyne Math Clock does not need to be plugged into a wall for operation. The perfect office clock for an engineer, an accountant, a mathematician or anyone else who works with numbers.
