There are 3 solutions: 181, 124 and 421 but this is not helping.

I wrote the numers in order from cells a1, a2 and b2. I didn't write b1=2 because it was compulsory.

Still the 1 solution I found remained. So the operator in this cage does not matter.

Yes it helps solving the 8^ cage (1 on column a, 8 and any other number on column b. But this does not help solving the main problem (written in post 8). Merry Christmas!

The main problem is the large 3 cage. It must be filled with {0,1,2,3}, but then some other operator must be faulty.

I try to show you “certain” steps, and indeed the way to the unique solution. Black: evident numbers/combinations; following orange, blue, green and red…

Very nice solution. I found another solution (for row 1 and 2). But the real problem is on row 3.

Attention, this is very unusual innovation but still with no more than 1 solution… The only solution I can see is if you've allowed the use of duplicate numbers. So the solution to the 2x2 you posted would be [2, 2]; [2, 2]. That's the only thing that makes this puzzle make sense for me.

That's the only thing that makes this puzzle make sense for me. Now it makes sense in relation to the “7×7” (already possible to see in my today’s sketch)…
