Hilariously Simple Math. The Combination Problem

Sheep, Chicken, and Goat need to take Farmer Ed's
money to the bank. The farmer wrote his code on
a piece of paper, but . . . Goat got hungry and ate it!
He remembers Farmer Ed saying there was
some kind of logic to the code. But what was it?

A hilarious comic that shows how much fun math can be.
For math fans and non-math fans ages 7 years and up.
