**the sum**of the digits in the "blocks" of cells of the corresponding column, and similarly, the numbers at the left of the first column, indicates

**the sum**of the digits in the "blocks" of the corresponding row. That is, in the first row (with three "blocks" of numbers), the digits of the first "block" must add to 11, those of the second "block" must add to 7, and those of the third "block" must add to 13. In the first column, there are two "blocks" of numbers, and the digits of the first must add to 23 and those of the second must add to 20, etc...
