Suppose you want to cook an egg for exactly 3 minutes. You have only a 5 minute hourglass timer and a 2 minute hourglass timer. Using these 2 timers, how can you boil the egg for exactly 3 minutes?

Set both timers off at the same time and put the egg in the water when the first runs out, take it out when the second runs out.

Start both timers, after the 2 minute one finishes you start to cook the egg. You have 3 minutes left on the other timer.
