- I heard many times that 0 is a pair number.
- I'm fairly sure that the definition of pair is multiple of 2.
- Yet I heard too that multiples of a prime number p are only 1 and p, therefore excluding 0.
So in the above contradiction, where is/are the false argument/s? I feel like despite what I heard, 0 is not a pair number or maybe only in informatics (that I started studying) which is still weird (the divergence I mean)
Thanks for your time.
