A Norwegian fella wants a job, but the dean won't hire him until he
passes a little math test

Without using numbers,
represent the number 9.

The Norwegian says, 'Dat's easy.' and proceeds to
draw three trees

What's this?'

Tree and tree and tree make nine,' says the
Norwegian.

Use the
same rules, but this time the number is 99

The Norwegian stares into space for a while, then picks up the picture
that he has just drawn and makes a smudge on each tree

How on earth do you get that to
represent 99

Each of da trees is dirty

dirty tree

dirty tree

dirty tree

Dat is 99

last question

Same rules

represent the number 100

he picks up the
picture again and makes a little mark at the base of each tree

The Norwegian 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

you got dirty tree and a turd

dirty tree and a turd

nd dirty
tree and a turd, vich makes von hundred

So, ven do I start?
