Expert Answer:
Prime numbers are defined as natural numbers with two distinct natural number divisors: 1 and itself. Thus the list of prime numbers starts from 2.
Negative numbers are not considered prime numbers as they have factors apart from 1 and the number itself, these factors are -1 and the absolute value of the prime number.
eg: -5 has factors 1, 5, -1 and -5 and hence is not considered prime.
Thus the set of prime numbers less than 10 are 2,3,5,7 and it is hence a finite set and we dont cosider the negative numbers.
