If you have correctly worked the puzzle up to this point, only box nine still lacks the numeral 8. This means you can scan the rows and columns that extend beyond box nine to determine the placement of the final numeral 8. Next, you can determine the placement of numeral 5 in box nine by scanning the rows and columns again. After placing the numeral five in box nine, only box eight lacks the numeral 5. Scan the rows and columns of box eight to determine which ones already contain the numeral 5 in the extended puzzle. What is the only numeral missing from column three? Write a numerical answer in the box provided.

Sudoku_4_Canvas Open the above file to read some history and see the puzzle that will be discussed. Copy the puzzle onto your own paper; be sure to indicate the nine individual boxes with dark lines. In this activity, we will use logical statements to solve a Sudoku puzzle. As we work, we will refer to the individual cells that hold a number as squares, and we will refer to the nine grids with dark outlines as boxes. The boxes will be numbered from one through nine in the same way that paragraphs are read in English, which is left to right and top to bottom. In a similar fashion, we will number the vertical columns from left to right as columns one through nine, and we will number horizontal rows from top to bottom as rows one through nine.
