This educational toy for youngsters gave you the features of the Little Professor in a handy plastic case. A nice feature of this game is an added buzzer to give some noisy feedback.

This product sold in Europe is identical to the Math...To Go! sold elsewhere.

The toy is intended for players ages 5 to 9.

Don't miss the similar Mickey Math Adventure based on the same technology.

The Professor 1.2.3 is featured in the Texas Instruments France SA leaflet Magiques et Intelligents dated 1991 and the Texas Instruments Deutschland GmbH leaflet Spielen macht schlau dated 1991.
