MathdokuPlace numbers into the puzzle cells in such a way that each row and column contains each of the digits from 1 up to the size of the puzzle(5).Like a Sudoku puzzle, no number is repeated in any row or column. Each bold- outlined group of cells contains a hint consisting of a number and one of the mathematical symbols +, x, -, /. The number is the result of applying the mathematical operation represented by the symbol to the digits contained within the domain. The solution to each puzzle is arrived at logically and is unique.
