Here are some: 5, -2, 1/3, square root of 27, pi.
The set of real numbers is a subset of the set of complex numbers. Any complex number can be represented in the form (a + bi), where a & b can be any real number, and i is the imaginary unit equal to sqrt(-1). So if b = 0, then we have just a, which is a real number.

How is a percent a real number?
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.
What isn't a real number?
A complex number for example. Complex numbers involve i, the imaginary square root of -1.
Can a number be real and complex?
Yes. If the number is like, for example, 3+0i, then you'll figure out that the number, though is written as a complex number, is actually a real number 'cause 0i=0 and 3+0=3 so you have both real and complex number. Every number is a complex number, no matter if it's imaginary or real or a combination of both (a+bi).
Is every complex number a pure imaginary number?
No. For example the number 1+i. Pure imaginary complex numbers are of the form 0 + a*i, where a is a non-zero real number.
Is -4 a nonreal complex number?
No. Negative four is a real number. All real numbers are also complex numbers, so it is a complex number (but it's real, not nonreal)
How is a percent a real number?
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.
Can a complex number be a pure imaginary number?
Yes. And since Real numbers are a subset of complex numbers, a complex number can also be a pure real.Another AnswerYes, for example: (0 + j5) is a complex number, whose 'real' number is zero.
What isn't a real number?
A complex number for example. Complex numbers involve i, the imaginary square root of -1.
Can a number be real and complex?
Yes. If the number is like, for example, 3+0i, then you'll figure out that the number, though is written as a complex number, is actually a real number 'cause 0i=0 and 3+0=3 so you have both real and complex number. Every number is a complex number, no matter if it's imaginary or real or a combination of both (a+bi).
Is the number 0 a complex or real number?
It is a real number because for example water freezes at 0 degrees Centigrade
Is every complex number a pure imaginary number?
No. For example the number 1+i. Pure imaginary complex numbers are of the form 0 + a*i, where a is a non-zero real number.
What is a non real complex number?
Complex numbers are written in the form (a+bi), where i is the square root of -1.A real number does not have any reference to i in it.A non real complex number is going to be a complex number with a non-zero value for b, so any number that requires you to write the number i is going to be an answer to your question.2+2i for example. (2 plus 2 times i)
Is one a real complex pure imaginary or nonreal complex number?
One is a complex number and a real number.
What do you get if you raise a real number to a complex number?
You get a complex number unless the real number happens to be 0 or 1.
Is -4 a nonreal complex number?
No. Negative four is a real number. All real numbers are also complex numbers, so it is a complex number (but it's real, not nonreal)
A number can be both real and complex?
Any real number is a complex number with an imaginary part equal to 0
Can you figure out two complex numbers that when mulitplied together become a real number?
3 and 5 are both complex numbers, and if you multiply them together, you get 15, which is a real number. If you were looking for two non-real complex numbers, then any pair of complex conjugates will work. For example, 5+2i times 5-2i is 29.
