The answer is 20.

Explanation:

First of all, the number -(-10) can be rewritten as +10 because the parenthesis act as a signal of multiplication between the negative sign outside the parenthesis and -10.

Thus, the expression can be rewritten as...

25+(-15)+10 (Now all you have to do is solve)
25+(-15)=10
And 10+10=20

That is how you can solve that question.
