You can put this solution on YOUR website! Re TY: "how many different ways can 4 stamps be attached together?"
With this wording..could mean
4 -horizontally(in a row) Or 4-Vertically (in a row)
2-across and 2-Down
3across and the 4th attached vertically to the other three and visa/versa
So...Yes, depending on what the question is asking...cold result in a different
combination of answers
......
If in a row(as in a roll of Stamps)
4! ways 4 'different' stamps be arranged in a row
