I've got a couple for you.
1. How do you divide 12 by 2 & get 7 without adding 1? It is possible. There may be a trick to it.
2. You're in a 10 ft. x 10 ft. steel room with no doors or windows. All there is in this room is a table & a saw. How do you get out?
The answers are
1. XII is 12 in Roman Numerals. If you divide anything by 2 you half it. If you take the bottom 1/2 off XII you're left with VII which is 7 in Roman Numerals.
2. You saw the table in 1/2. 2 halves make a w(hole) you crawl through.
1. is very clever... I like it.
2. Oh no... Head in hands... that's terrible.
