And increasing negative voltages makes the number bigger.
Positive and negative are polarities not quantities. If you go from -45v to -50v, that's a 5v increase. You are now 5 volts farther away from the potential of your ground. You can't have a positive and negative dc voltage on the same wire, at least for the sake of this explanation.
