During the first lesson with your new and rather eccentric mathematics teacher he continues his tradition of telling the class that if anyone can guess his favourite mathematician they will be let off homework for the rest of the year. However, if you make a wrong guess you are duty bound to wash his car every week for the rest of the year. In all the years he has taught, the sparkle on his car has been the envy of every other teacher. Despite this seemingly impossible challenge, one person has managed to work it out... your older brother!
Of course he is not going to tell you the answer, but after a little "research" you find two scraps of paper hidden inside one of his books. The first piece seems to hold a clue.
The second piece is obviously the answer you are seeking.
