2 9 47 5 36 1 8 filling skills: 1. First, find the middle number in a group of numbers, and fill it in the middle of the grid. 2. Calculate the sum of the group numbers, and determine the average number (i.e. the sum of the numbers in each row or column, e.g. 45 / 3 = 15). 3. The maximum and minimum numbers can not be filled in the corner, but should be filled in the opposite side
