On a Sunday morning approaching noon at a traffic light intersection in Jakarta, Alvin (7), Riki (7), and Jaki (7), three young silver buskers, were doing their usual routine. A Korean tourist gave them a 50,000 won Korean currency note. However, due to their limited education and knowledge, they had to figure out how to divide the money equally. They tried various methods, but all failed, until they finally met Arif (23), a mathematics teacher.
