Don’t worry … there’s NO math. Think of this puzzle as a process of elimination. The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 subgrids or boxes contain all of the digits from 1 to 9. There should be no duplication of a digit in any row, column, or subgrid/box. Have fun!
