Read the problem, mind the signs, and write the final result.
At dusk the temperature was 5 °C. Overnight it fell by 8 °C and by morning it had risen by 3 °C. What is the morning temperature in °C?
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.
