Answer:
10
Explanation:
because if you look at:
-(-8)
it shows 2 negatives. and parentheses means to multiply,
And a negative times a negative equals a positive.
So -(-8) is also like -1x-8
they both equal (Positive) 8.
so if you put 8 back in the question it will be:
2+8
so it equals 10
I hope this helps :)
