Two trains are on the same railroad track; one is headed east the other west, they both leave the station at 1:00 and are travelling at the same speed. Yet they didn't crash into each other. How can this be?
They went at the same time but one went at 1:00 in the afternoon and one went at 1:00 in the morning.
Using only addition, how do you add eight 8's and get the number 1000?
