Two matchsticks have to be moved to get the exact time half past four.
What squares those two moved matchsticks belong to?
One matchstick belongs to the 1st square, the other one – to the 2nd square. Transforming the 1st square into the “4” and the 2nd square into the “3”, creates the time 4:30, or half past four.
