The equation is -10+(-15). So you take -15 out of the parentheses and you get -10-15 because if you add a negative number then it's just subtracting. So -10-15 is -25. Because 15 less than -10 is -25.
The answer would be 5 (positive) because a negative and a negative = a positive 

If you have a iPhone you can calculate negatives, fyi
