Mathematics of Sudoku

Sudoku is a game where you have to fill in a 9x9 grid with numbers. Each row, column, and 3x3 box in the grid must contain all of the numbers 1 to 9. To play Sudoku, you have to use logic and problem solving skills to figure out which numbers go where. Mathematics is used to help figure out which numbers need to go in each box, row, and column. We can use mathematics to figure out which numbers are missing and which numbers can appear multiple times in the same row, column, or box. Mathematics is also used to solve some Sudoku puzzles with more than one valid answer.
