Answer:

-10+(-10)=-20

Step-by-step explanation:

This is incorrect because this is basically saying -10-10=? When is says to add outside of the parentheses and has a negative sign in it you always ignore the addition because it means that you have negative 10 and you are "adding" another negative 10 to it.
