One day Addy sees a poster in school for joining a Math league. She rushes over to Uno and tells him he should join, showing him the poster that says the winners of the state math tournament would win new bikes. Uno is immediately uneasy about the whole idea. He prefers doing his calculations in private, and bikes are quite possibly his LEAST favorite thing in the world. Addy says SHE would get the bike, and HE would get the glory. Not wanting to disappoint his good friend, Uno begrudgingly signs up.
