Real numbers are those which can be placed upon a number line stretching to infinity in both directions. To be "not real" you must be unable to do that. We call "not real" numbers "imaginary" numbers. They are numbers which are derived from the square root of -1. If you think about it, what number can be multiplied by itself and you end up with -1. In the real numbers, there isn't one. So we have imaginary numbers. They are written using Euler's notation where i represents the square root of -1. So, to answer your question, i is a "not real" number.
2 is a real number.
The square root of 2 is real number but it is not rational number because it can't be expressed as a fraction.
Any odd root, for example the cube root, of -3.24 is a real number.

No, the devil's phone number is not real. Many associate the numbers 666 with the devil.
Sorry, we do not do diagrams
2 is a real number.
0 is a real number.
The answer depends on where real number!
No. The square root of negative one is an example of an imaginary (not real) number. Pi is irrational, but real.

The number of questions answered here over the numbers of questions trashed because they cannot be answered.
An irrational number is a real number that cannot be expressed as a ratio of two integers, pq/ where q > 0. sqrt(2) and pi are examples.
2 is a real world prime number.
A real world example of what? Math in general? Geometry nets? Name the math concept and it'll be easier for readers to give you a real world example.
It need not be. For example, a complex number as a percent of most other complex numbers, or any real number, will not be a real number.
