What makes you think two is prime? Not everyone would agree with that statement as the artical points out.

The article states that historically Nicomachus of Gerasa didn't consider 2 a prime, in like 100 AD.

Nowadays 2 is considered prime. Seems silly to question why someone is claiming 2 is prime if that is how it is defined in modern day.

> What makes you think two is prime

The current mathematical definition of a prime number

No respect for Nicomachus of Gerasa, huh?

I will admit that for me it was being brainwashed through years of high school and university mathematics.
