So, if you are talking about a 4x4 grid, does the total number of possibilities change when you "add" in the 4 different procedures??........not a Mathematician, but Iwouldn't think so??
If you have 1 and 4 in a two-cell cage, the operation could be 5+, 3-, 4x, or 4/. The grid, or Latin square wouldn't change, but it would be a different puzzle.
