Answer:
The answer is -26
Explanation:
To solve negatives you just need to add regularly but the add the - sign.
If you need any more help let me know.
-11 + (-15) = -26
When adding a negative number with a negative number you will simply just add the two numbers together and the sign of the answer will be negative as well.
Hope this helped!
