The game board Oware used in West Africa may be used in calculations in much the same way that the abacus is used in Asia. For Africans this Oware board is a forgotten calculating instrument that need be taught in schools
The Board functions as a two register computer when manipulated by the operator to perform various operations
The Oware Calculus App teaches the computing science behind the board, how to represent numbers on the board, the primitives needed to manipulate numbers on the board and how to do various operations
The operations illustrated include basics, single digit addition, addition, up counter, difference, negate and subtract
There is a simulator provided for each operation so that user can enter numbers, execute tasks and see the steps occur
For additional information refer to the book on Oware: The Forgotten African Mechanical Computer by Prof. Nii Quaynor
