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.
