    a composite number is a whole number that can be written as a product of two other whole numbers (not including itself and 1) another way to say it is a composite number is NOT a prime number

    here is an example 6 is composite because \(6=3\times 2\) 7 in prime, because it only has itself and 1 as a factor

    that is really all there is to it the only part that might be confusing is that 1 is not prime or composite, and 2 is prime yeah sort of but even odd only means divisible by 2 9 is composite because \(9=3\times 3\) but it is not even

    the numbers you have to consider are \[\{2,3,4,5,6,7,8,9,10,11,12\}\] can you tell which ones of those are composite and which are prime?

    i am not interested in choices particularly more interested in if you know which numbers are composite then it is only a matter of counting
