Unreal numbers are complex numbers and numbers of higher order. There are infinitely many of them. It can be shown that the cardinality of complex numbers is the same as that of real numbers: this cardinality is called the continuum, C.
There are À0 (aleph-null) counting numbers or integers or rational numbers - the "smallest infinity"!!!. C is equal to 2À0.

Are unreal numbers significant?
Yes, they are.
Are unreal numbers undefined?
Yes.For example, any number divided by 0 is unreal. There is no defined representation of (i.e.) 12/0.
Are all unreal numbers irrational?
No. Irrational numbers form a proper subset of real numbers. That means that all irrationals are real so non-reals cannot be irrational.
What are examples of real numbers?
1,2,3,4,5,6,1/2, 3/4 these are all real. the square root of negative is an unreal number.
What is a antonym for the word real?
