With the beautiful MATH MAGIC Texas Instruments introduced a variation of the Little Professor. The Little Professor gives you one of ten-thousands pre-programmed math questions and you have to type the correct answer. The MATH MAGIC works different: You have to type the question and the answer ! The MATH MAGIC gives you only a correct (flashing display) or wrong (EEE) answer. 

Similar educational products are known from National Semiconductor with the Quiz-Kid and Radio Shack with the wonderful Monkey See. Both use simple green and red indicators to state correct and wrong. 

The technology is based on the first Little Professor introduced one year earlier. The printed circuit boards are indentical, only the right sliding switch is missing.

Don't miss the rare Battlestar Galactica introduced in 1979 - an almost perfect copy of the MATH MAGIC.
