OK. I have an exam lately in my computer lesson – Basic Switching Theory.
One of the question is that:
Make a logic diagram outputs HIGH when the input is a prime number.
After the exam, some of my classmates told me that 0 and 1 are neither composites nor primes. I asked them why, but they didn’t answer me. They only said that it is JUST they’re not composites nor primes.
I am really confused. And because of that i am now unsure of my answer. HELP.
The number 1 is not prime because, by definition, primes are greater than 1. If 1 was prime, then the Fundamental Theorem of Arithmetic wouldn’t hold, and that would be a Bad Thing.
The number 1 is not composite by definition.
