Matt points out that this is interesting - however he missed the fact that it is no-operator (i.e. it is unique without giving the operators - or bothering to mention the 10). {He might mention this in his solution which I have not looked at.}

I would also guess that 1(2), 2(2), 5(2), 8(3), 12(3) with orthogonally connected cages is also unique -thoughts?

I'm afraid I (once again) have to embrass you here a little bit. :twisted:

I didn't miss "the fact". In fact I have explored that no-op possibility way before you did, and found 2 solutions:

Code:
.-------.-------.
|2      |8      |
|       |       |
:---.---'---.   |
|1  |12     |   |
|   |       |   |
|   |   .---'---:
|   |   |5      |
|   |   |       |
:---'---'-------:
|               |
|               |
'---------------'

2143
4321
3214
1432

4231
2314
1423
3142

So yeah, this puzzle (even though so tiny) has to be taken with operators. :idea:

OK

I checked it a few times on paper (in a pub with my first few drinks after being bugged up for three days) and was pretty sure of it before posting. But then again I've made mistakes before - must try harder!

On looking at your solution I missed the 12*(3) = 223 so my initial (with operators) solution was faulty anyway!
