Calcudoku Sample

Rules: place 1 - 6 in each row and column. As with killer sudoku, the grid is divided into coloured segments, however this time they might not be addition sums, but could also be subtraction, division or multiplication, as shown by the sign at the start of each region. With addition or multiplication order is irrelevant, but with subtraction and division you should start with the highest number and divide or subtract the lower numbers from that highest number in the region. Repetition of numbers is allowed inside the coloured sum regions, making calcudoku an interesting twist on other forms of sudoku.
