An elderly man wants a job, but the foreman won’t hire him until he passes a little maths test:
“Here is your first question.” The foreman says.
“Without using numbers, represent the number nine?”
Without numbers?”
The old man says. “That’s easy.”
And he proceeds to draw three trees.
“What’s this?” The boss asks.
“Have you no brain? Tree plus tree plus tree makes nine.” Says the old man.
Fair enough.” Says the boss.
“Here’s your second question. Use the same rules, but this time the number is 99?”
