Number Riddle


This is a tricky one as there is no addition sign connecting the first n second row and also no addition size between second and third row…once you figure this out the solution is easy.

So it is not

1+1+1+1+1+1+1+1+1+1+1×0+1= 12

But actually;

1+1+1+1+11+1+1+1+11+1×0+1= 30

So the answer to the puzzle is 30
