Step-by-step explanation:
because because that would be subtracting positive 10 by -10. not adding -10 + -10 which would be 20
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.
HOPE THIS HELPS XDDDDD
