The mathematical statement 4 C A means? The c is not a c it means its part of a set or something..

Hi Taylor!

Did you mean 4∈A ?

Cuz there's a BIG difference between 4⊂A and 4∈A. 4∈A means that A is a set which contains different elements, and 4 is one of those elements. 4⊂A means that 4 is a subset of the set A, but most mathematicians don't say that numbers are themselves subsets
of anything-- that's weird. It's more correct to say {4}⊂A. But that's kinda nitpicky... which is why I think you meant 4∈A.
