Number Names Think of any number from 1 through 100. (Say 10) Write down its name. (ten) Count the number of letters in its name to obtain a second number. (3 letters) Count the number of letters in the second number to obtain a third number. (three,5 letters) Continue in this way until the chain of numbers ends on a number that keeps repeating. What is the final repeating number? It will always be the same number. Why ? Created by Martin Gardner.
