Answer:1115
Explanation:
8 is greater than 3 so you must regroup:
Take 1 from 1, so 1 becomes 0.
Add 10 to 3, so 3 becomes 13.
13 minus 8 is 5
9 is greater than 0 so you must regroup:
Take 1 from 3, so 3 becomes 2.
Add 10 to 0, so 0 becomes 10.
10 minus 9 is 1
2 minus 1 is 1
2 minus 1 is 1
Andd the answer: 1115
If it is the other way it is -1115.
