Novus was a consumer products division of the National Semiconductor Corporation, a major supplier of integrated circuits. In 1975 they introduced a mid-range series of handheld calculators called "The Professionals". The Novus 4510 'Mathematician' was the cheapest and most basic in the range, and is a basic scientific calculator.

The Novus 4510 Mathematician calculator has an eight-digit red LED display and is powered by a 9 volt battery. It has an off-white case with a matte black keyboard label that has silver trim. It has an on/off switch on the left side near the top and a jack for an AC adapter on the top right side. This machine was also known as the National Semiconductor Mathematician and the Novus 4510. The Mathematician uses Reverse Polish Notation (RPN), like many scientific calculators of the time. The calculator has an eight-digit LED display and did not support scientific notation or overflow, as a result anything over 99999999 would cause an error and the calculator would display '.0.0.0.0.0.0.0.0.'.

The calculator was powered by a PP3 battery or a mains supply.

Our calculator has serial number of 105922 and is complete with the soft case, AC adaptor, and Operations Guide. It was very kindly donated by John Anthony (Tony) Kidd.
