Town Mission 15: Aristo's Challenge

Town Mission 15: Aristo's Challenge is the 15th mission in Sonic's story in Sonic the Hedgehog (2006). It takes place in New City, Soleanna. A man called Aristo gives Sonic a few math questions, to which the answers are numbers, and Sonic must answer them all correctly.

Guide
This Town Mission is very unique, in that it requires no running around and generally minimal input from the player. Aristo asks the player a math question, and subsequently, wooden crates marked with the numbers 1 to 9 appear in the area. The player is required to run up to the crate with the number that correctly answers the question and kick it to destroy it. This process is repeated for all questions.

Getting any of the answers incorrect will force the player to restart the Town Mission, and getting all answers correct clears the mission.
