Re: Help with countinig principle

Any good links to websites explaining the counting principle? Because I'm not sure I understand it from your explination. Is it simply that you can match ever item in a cell, with every item in every other column except items in the same row as itself?

(i.e. that's why you didn't match A to C in either of your examples, or B to D in the third example)?
