Geometry always kicked my behind. :wink: Haven't a clue.
Here's an age-related math puzzle:
Corrine asked her Granny how old she was. Rather than giving her a straight answer, she replied:
"I have 6 children, and there are 4 years between each one and the next. I had my first child (your Uncle Peter) when I was 19. Now the youngest one (Your Auntie Jane) is 19 herself. That's all I'm telling you!"
How old is Corrine's Granny?
