Yes.For example, any number divided by 0 is unreal. There is no defined representation of (i.e.) 12/0.
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.
No. Irrational numbers form a proper subset of real numbers. That means that all irrationals are real so non-reals cannot be irrational.
No, they are quite real. It is just that in some situations it makes sense to use negative numbers, in others not.
sureal not real or unreal fake phony false faux imitation wrong imaginary (numbers)

We call them imaginary numbers, like the square root of negative one.
I think you mean rational. No, there are irrational numbers, like pi, and unreal numbers, like 2/0
231.57 has five significant figures/numbers. All the numbers in 231.57 are significant.

All nonzero numbers are significant.
Yes, unreal is an adjective
Unreal happened in 1998.
Yes, unreal is an adjective.
Three. All nonzero numbers are significant, and any zeros in between significant numbers are significant.
When multiplying numbers with significant figures, round the final answer to match the number with the least significant figures in the original numbers.
