Rules for playing Kendoku

Fill in each square cell in the puzzle with a number between 1 and the size of the grid. For example, in a 5x5 grid, use the numbers 1, 2, 3, 4.& 5 Use each number exactly once in each row and each column.The top left corner of each cage (indicated by heavy lines) has a “target number” and a math operation. The numbers you enter into the cage must combine in any order to produce the target number using the math operation noted (+, –, x, ÷) A number can be repeated within a cage as long as it is not in the same row or column. Two hint numbers have been already placed in the grid to start you off.
