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: 2835 sottrazione 6678 sottrazione 5267 sottrazione 5054 aggiunta 3830 aggiunta 8886 sottrazione 2169 aggiunta 8463
Solution:
