Question

-5/6+ -5/6 please help me

Answer 1

0 because same negative is same space drone zero

Answer 2

(-5/6)+(-5/6) have the same denominator (number at bottom of fraction), so all you have to do is add the numerator(top number). So -5 +-5 =-10 . Now you have -10/6, which simplifies to -5/3. 
Hope this helps :)
