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: 4480 sottrazione 4872 aggiunta 4467 sottrazione 1850 sottrazione 1153 sottrazione 3842
