Teacher: 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'.
Teacher: Now, understand the problem? If you are still confused, see the following example:
10 sottrazione 7
Solution: 3
Reason: Here, 'sottrazione' represents the subtraction operation. So, the answer is 3 (10-7=3).

Now, solve this instance: 5681 aggiunta 9148 aggiunta 2486 sottrazione 4981 sottrazione 5607 sottrazione 8565 aggiunta 7296
