Actual Discussion With My Son
I, the owner of a degree in Mathematics and a degree in Computer Science from Seattle University, had the following discussion with my 7 year old son, who recently graduated from first grade.
Andrew: Dad, did you know the square root of 0 is 0?
Dad: That is correct. 0 is kind of a unique number, 0 times 0 is 0.
Andrew: Dad, the square root of 1 is 1 and 1 times 1 is also 1. So 0 is not that unique.
Dad: I need to call Seattle University and ask for a refund.
