Composite numbers are every number that isn't prime so realistically any number that isn't prime in a problem you have in life is composite. Like say you're making a collage and you have an 16x16 inch page. You have 4 4x6 inch pictures and 2 2x3 inch pictures. You want to make sure you have enough space for them all with out over lapping them so you multiply 16 and 16 to get the total area of the page of 256 inches squared. Then you multiply 4 and six to get 24 then multiply that by 4 and get 96 in squared. Then you do the same thing with the 2x3 inch pictures and get 12 square inches. Add the two picture areas together to get 108 inches. Now you subtract 108 from 256 and get 148. 148 inches is the amount of space you have to fill up with stickers or words or basically what ever you want.

The composite number out of this group of numbers would be 4.
I wouldn't. The national debt is a real world situation and it's a composite number, but its composite-ness has no bearing on the problems it causes.
Yes, there is an infinite amount of prime numbers. This has been proven by the ancient Greek mathematician Euclid. As for composite numbers, since there are infinitely many natural numbers, there must also be an infinite amount of composite numbers, as they are all the natural numbers that are not prime.
It would probably refer to a digit that is a prime number, or a composite number. Note that mathematicians normally talk about prime and composite NUMBERS, not individual digits.
the numbers between 31 and 41 are 31,32,33,34,35,36,37,38,39,40, and 41. Composite means that there are two or more factors. The composite numbers here would be: 31, 37, and 41. I am a math geek so this has to be correct.
