Splinter wrote a three-digit number on the board. Then he asked each of the four Teenage Mutant Ninja Turtles (Leonardo, Raphael, Donatello, and Michelangelo) to count the number of letter in his name. (Donatello has 9 letters in his name.)
Splinter said that for each turtle, the number of the board minus the number of letters in the turtle's name is evenly divisible by the number of letters.
Each turtle confirmed that Splinter was right.
