Despite the general notion that no mathematics knowledge is required to solve a classic sudoku puzzle, sudoku can be used as a teaching aid in mathematics. I have contributed a sudoku puzzle to the August 2008 issue of NRICH.

The NRICH Project is based in both the University of Cambridge's Faculty of Education and the Centre for Mathematical Sciences. It is also part of the family of activities in the Millennium Mathematics Project.

My sudoku creation ("Multiplication Equation Sudoku") illustrates the concepts of multiplication and equations.
