COMBIN
 

I want to be able to print a chart that shows the possible combinations of
numbers that could be used to add to a larger number. For example...What are
the 2 space combinations for the number 17? 9,8 What are the 3 space
combinations for the number 17? 179,269,278,359,368,458,467 These are needed
to play the game
Kakuro or Killer Sudoku or Cross Sums. I'm sure I should be able to do that
in Excel but I can't figure out how. Also I am a beginner so any answer needs
to be in very,
very simple or well explained format. Thank You
