Answer:

Voltage difference is 13 volts

Step-by-step explanation:

If voltage A ( $V_A$ ) is -8 volts, and voltage B ( $V_B$ ) is 5, the voltage difference is calculated via the formula

$V_B-V_A=5\,volts \,- \,(-8 \,volts)=5\, volts\,+\,8\, volts=13\,volts$

When estimating a difference between quantity A and another quantity B it is custom to perform the difference built as the last quantity mentioned, minus the first one.
