Question

A number that is neither prime nor composite is _____. a. 6 b. 9 c. 1 d. 3

Answer 1

Answer:

Zero

So a composite number is one which is not a prime number or 1. Sometimes, the term composite number is used in a wider sense to include negative integers; a negative integer is composite if it is the negative of a (positive) composite number. Zero is neither prime nor composite.
