Why is (a + b)* a regular language?
The language (a+b)* is regular as there is a regular expression for it.But this language contains all possible strings. So it should imply that regular language is the super-set of all languages, but clearly it isn't! Subsets like $a^{n}b^{n}$ are not regular. Can someone tell me what am I missing?
