Geniac Analog Computer was built and sold by Burstain-Applebee Co. as a basic introduction to the general method of operating analog computers. It has an accuracy in multiplication and division of about 5%, though it could be increased somewhat by means of certain tricks offered by the manufacturer. With such accuracy the purpose of the computer was not to serve as an accurate computing device, but rather as an estimating machine. The Geniac Analog Computer is capable of the following calculations:
- Multiplication
- Division
- Roots
- Powers
- Calculation of a compound interest
- Trigonometric formulas

Geniac Analog Computer is virtuall identical to Calculo Analog Computer that was designed and manufactured by Science Material Center, Inc. since 1959.
