Dear All,
Happy New Year.
Started this 7x7 fine: Noticed that 125 = 3^5
So most of the cages for row 1 and column a can be pencilled in.
The '5 mod' at b4 is either (5,6) or (5,7)
After that I am stuck.
I can see that the cages 11+ at b2 and 10+ at c3 m u st both contain either a 6 or a 7.
But I just can't get any further.
Tips? Suggestions? Help!
Many thanks
EG

* I used the 3- cage at d2;
Which number must be filled in at d2? This in relation to the sum of b3 and g3
With most possible solutions I got stuck quickly.

* 112x cage has few possible solutions
