What does the generator do?
The generator alternates three scenarios — temperature, account balance, diver elevation — using small numbers so the signed answer is easy to interpret.
How to solve
Translate each action into a signed change: a fall is negative, a rise is positive, money spent is negative, a refund or deposit is positive. Add all changes to the starting value. Always check the sign of your final answer.
