In the standard game of sudoku, what should the nine numbers in a single row add up to?
Sudoku is a logic-based, combinatorial number-placement puzzle. In standard sudoku, the objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 subgrids that compose the grid (also called "boxes", "blocks", or "regions") contains all of the digits from 1 to 9. The puzzle setter provides a partially completed grid, which for a well-posed puzzle has a single solution.
As all the numbers from 1 to 9 are used in each and every single row they would add up as such:
1+2+3+4+5+6+7+8+9 = 45
Therefore the nine numbers in a single row would add up to 45.

What scares most people away from sudoku is fear of math, when, in fact, there is no math involved: it’s pure logic and spacial relationships. Actually, sudoku could be played with any nine distinct items: kinds of fruit, for instance.

Martha Calkins, Interesting. I never thought about using other objects. I have done logic problems, like if the following five people each bought a different flavor of ice cream on a separate weekday, with each owning a unique pet, and living on a distinct street, then fill in the grid. The hints could be matching one person to a pet, street, and weekday. Thank you, Christine, James' wife

Had to do a little head math! 😀

I played 100 sudoku puzzles in the last week and never added them. This is a nice bit of trivia that sodoku players will never use.

When playing sukodu, nobody bothers to add the numbers 1-9.....!!

Each line each column and each square of 9.

1 in 3 could not be bothered to simply add the numbers 1 through 9 together to get the answer.
