In this task you will be given an arithmetic operation in Italian and you have to find its answer. The operations 'addition' and 'subtraction' have been replaced with their italian translations i.e you need to perform addition when you see 'aggiunta' and subtraction in case of 'sottrazione'.
One example: 10 sottrazione 7
Solution is here: 3
Explanation: Here, 'sottrazione' represents the subtraction operation. So, the answer is 3 (10-7=3).

Now, solve this: 4731 sottrazione 6980 aggiunta 3197 sottrazione 9605 sottrazione 2237 sottrazione 217 aggiunta 1243
Solution:
-9868
