No, not every number in the eighties is composite. A composite number is a positive integer greater than one that has more than two distinct positive divisors. In the eighties, the numbers 81 and 85 are composite because they have divisors other than 1 and themselves. However, the number 83 is prime because it only has two divisors, 1 and 83.

Well, honey, let me break it down for you. A composite number is any number greater than 1 that can be divided by more than just 1 and itself. So, when we talk about the numbers in the 80s, not all of them are composite. For example, 81 is a composite number because it can be divided by 3 and 27, but 83 is a Prime number because it can only be divided by 1 and 83. So, not every number in the 80s is composite, but some are.
