10+2 The second row of cat heads =20, and the cat heads are 5.
5+2 cat claws in the third row =9, and two cat claws are 2.
So every cat's paw is 1.
If you look at the picture carefully, you can see that cats lack claws, so it is 10- 1.
The final result is 5+1* (10-1) =14.
Thank you for your adoption.
