Put one digit from 1–9 in each square so that the following two conditions are met: 1) each row, column, and 3-x-3 box (as marked by shading in the grid) contains the digits 1–9 exactly one time, and 2) the sum of the numbers in each area marked by heavy black lines is equal to the little number given in each of those areas. For example, the digits in the upper-leftmost square in the grid and the square directly to its right will add up to 10. Now quit wastin’ my time and solve!
