You probably know that half of 12 is six. But the other day, I caught a glimpse of a clock peeking between buildings. At that moment, I noticed that sometimes, half of 12 is seven. How is this possible?

Scroll down for the answer!

Clocks often have their numbers in Roman numerals, so 12 is written XII. If you cover the bottom half of XII, you’ll get VII, which is seven in Roman numerals!
