A Jamaican man?

A Jamaican man wants a job,but the foreman won't hire him until he pes a little math test."Here is your first question," the foreman said."Without using numbers,represent the number 9.""Without numbers?"The Jamaican says,"Dat is easy."And proceeds to draw three trees."What's this?"the boss asks."Ave you got no brain?"Tree and tree and tree make nine,"says the Jamaican."Fair enough,"says the boss."Here's your second question.Use the same rules,but this time the number is 99."The Jamaican stares into space for a while,then picks up the picture that he has just drawn and makes a smudge on each tree."Ere you 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 Jamaican,so he says,"All right,last question.Same rules again, but represent the number 100.
