Possible example of real number?
0 is a real number.
Which real number contains additive inverses for all its elements?
The question is confusing. The additive inverse of a real number is the same number with the sign changed. For example, the additive inverse of -5 is +5 (or simply 5); the additive inverse of 7 (which is the same as +7) is -7.
Is pi an Example of a number that is not real?
No. The square root of negative one is an example of an imaginary (not real) number. Pi is irrational, but real.
What is a real world example of a prime number?
2 is a real world prime 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 is an example of a rational number an integer and a real number?
1/2, 5, pi, respectively

What is an example of not a real number?
i
What is a real world example of a prime number?
2 is a real world prime number.
Is -5 a natural or real number?
Real
Is 5 squared a real number?
Yes, Any real number squared is a real number. In this case that number is 25.
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.
Why is quotient of a number divide by itself?
Any real number (besides zero) divided by itself is equal to 1. In algebraic terms, if x is a non-zero real number then x/x=1. Zero is the exception because dividing a number by zero is undefined. For example 5 divided by itself is 1. 5/5=1
What is the sum of two complex conjugate number?
Since the imaginary parts cancel, and the real parts are the same, the sum is twice the real part of any of the numbers. For example, (5 + 4i) + (5 - 4i) = 5 + 5 + 4i - 4i = 10.
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.
