When I was six, my class was given an arithmetic test at school. One question said:
"Write a story about the sum 12+4=16."
And I was confused about this, because it happened that I'd been away on the day when they explained about word problems. I had no idea at all what the question could be asking for. After several minutes of thinking, I wrote:
"One day, the sum 12+4=16 went out for a walk. Then it came back. The end."
