20+(-15)=5
You just took 15 from 20. When adding negative numbers to positive ones, you move LEFTWARD on the number line toward 0 (because that's where the negative numbers are).
As I understand the question:
If 20 and a number (x) = a negative 15 (-15), then you can write it out as an equation to get the answer:
20 + x = -15 is the equation (x represents the number)
20 - 20 + x = -15 - (-20) (what you do to one side you must do to the other)
x = -35
Therefore, the sum of 20 and -35 is -15.
