Which of the given numbers are composite?
0, 1, 15, 19, 23, 31, 49, 55, 59, 87, 91, 97, 103, 105
Scooby, what is a composite number?
i am not sure
If you don't know what a composite number is, how can you possible identify one when you see it? See this site.

To determine which numbers are composite from the given list, we need to understand what composite numbers are.
Composite numbers are positive integers that have divisors other than 1 and themselves. In other words, they are numbers that can be divided evenly by at least one integer other than 1 and the number itself.
Now let's go through the list of numbers:
0: 0 is not a composite number because it is neither positive nor negative. It is a neutral element for addition and subtraction.
1: 1 is not a composite number because it only has one divisor, which is 1.
15: 15 is a composite number because it can be divided evenly by integers other than 1 and itself. For example, 15 can be divided by 3 and 5.
19: 19 is not a composite number because it only has two divisors, which are 1 and 19.
23: 23 is not a composite number because it only has two divisors, which are 1 and 23.
31: 31 is not a composite number because it only has two divisors, which are 1 and 31.
49: 49 is a composite number because it can be divided evenly by integers other than 1 and itself. For example, 49 can be divided by 7.
55: 55 is a composite number because it can be divided evenly by integers other than 1 and itself. For example, 55 can be divided by 5 and 11.
59: 59 is not a composite number because it only has two divisors, which are 1 and 59.
87: 87 is a composite number because it can be divided evenly by integers other than 1 and itself. For example, 87 can be divided by 3 and 29.
91: 91 is a composite number because it can be divided evenly by integers other than 1 and itself. For example, 91 can be divided by 7 and 13.
97: 97 is not a composite number because it only has two divisors, which are 1 and 97.
103: 103 is not a composite number because it only has two divisors, which are 1 and 103.
105: 105 is a composite number because it can be divided evenly by integers other than 1 and itself. For example, 105 can be divided by 3, 5, and 7.
Based on this analysis, the composite numbers from the given list are: 15, 49, 55, 87, 91, and 105.
