Mars is in to maths in a big way. He seems to have a natural flair for it, but it also helps that his parents are both good at maths and his Grandpa is a mathematician who has been tutoring him from an early age.
Lately his favourite trick is to wait until I'm really really tired and then ask me "what's a hundred times a hundred?" Without thinking I invariably answer "a thousand" and then he crows about how he managed to trick me.
Today on the way home from church I overheard this conversation.
"Venus, what's a hundred times a hundred?"
She replied "Two. What's plus equals?"
He thought for a moment and hesitantly offered "Three?"
She giggled and said "No, four!"
I guess Mars doesn't know everything, not yet.
