Norwegian Math Test

Ole wants a job, but the foreman won't hire him until he passes a little math test.

Here is your first question, the foreman said. 'Without using numbers, represent the number 9.'

'Without numbers?' Ole says, 'Dat's easy.' and proceeds to draw three trees.

'What's this?' the boss asks.

'Vot! You got no brain? Tree and tree and tree make nine,' says Ole.

'Fair enough,' says the boss. 'Here's your second question. Use the same rules, but this time the number is 99.'

Ole stares into space for a while, then picks up the picture that he has just drawn and makes a smudge on each tree. 'Dar ya go.'

The boss scratches his head and says, 'How on earth do you get that to represent 99?'

'Each of da trees is dirty now. So, it's dirty tree, and dirty tree, and dirty tree. Dat is 99.'

The boss is getting worried that he's going to actually have to hire this Norwegian, so he says, 'All right, last question. Same rules again, but represent the number 100.'

Ole stares into space some more, then he picks up the picture again and makes a little mark at the base of each tree and says, 'Dar ya go. Von hundred.'

The boss looks at the attempt. 'You must be nuts if you think that represents a hundred!'

Ole leans forward and points to the marks at the base of each tree and says, 'A little dog come along and pooped by each tree. So now you got dirty tree and a turd, dirty tree and a turd, and dirty tree and a turd, vich makes von hundred.'

'So, ven do I start?
