Dear Dr. Billingham
Thanks for the wonderful lesson and story. I am a 30 year old adult and have always been a bit short on Mathematics knowledge. Lectures/lessons like yours help me to stay motivated to learn mathematics even at this point of age.
In the first part of the story, you said the number of the frogs have to a whole number, and the number that the Princess saw was 23.2, do you think 23.2 is a whole number?
