-4/5 + (- 1/3)
= -4/5 + - 1/3
If 2 signs (+ or -) are so close together that you can put a circle around them without anything else inside the circle
then
if the signs are the same, replace with a plus
if the signs are different, replace with a minus.
= -4/5 - 1/3
then, either find a common denominator and solve that way or just do it on your calculator.
If doing by hand,
consider -8-6 = -(8+6) = -14
