Question 122152: I am trying to find number concepts on an assignment called Chapter 2 More Number Concept Creatures: Wollygoggles and Other Creatures from 1980 Cuisenaire Company of America book.
I am stuck on pg 34 & 35.
They are find the common rule for 1) 3 -> 3, 81 -> 9, 100 -> 1, 17 -> 8,and 121 -> 4 and the next one is find the common rule for: 14 -> 4, 25 -> 10, 50 -> 0, 75 -> 35, 111 -> 1.
the first number of each is in a circle (the input) and the second number is in a square (the output).

etc.
