Normal sudoku rules apply. The digit on an arithmetic symbol is the result of performing that operation on the cells it points to, i.e. the digit on a + is the sum of the four orthognally adjacent cells, a ×the product of the four diagonally adjacent cells, a - the difference between the two horizontally adjacent cells, and a / the quotient of the two adjacent cells on the positive diagonal. The digit on a cell outside the grid is the number of digits seen looking into the grid, where higher digits block the view of lower digits.
