Congratulations to Fiffy, Nahan, and Haruka, all Grade Eight students, who walked 93 stairs, counted 44 student chairs and 12 teacher chairs in the cafeteria, tallied the 17 green chairs in the auditorium and the 19 windows in the gym, remembered that the RIS family comes from 21 different countries, and enumerated the 7 teachers with an 'r' in their name. After doing some fancy and correct calculations, they have each earned the title of I-Know-My-School Math Puzzle Master of the Week! Well done!
congratulation~!
