Wrong! Not only is zero a real number, but it is the additive identity for the set of integers, rational numbers as well as real numbers.
Zero is a an integer and, since all integers are real numbers, zero is a real number.
Yes, zero is a real number. It is not a counting number, but it is an integer, a rational number, and a real number.
not a real number * * * * * Zero is very much a real number. In fact it is the additive identity for the set of real numbers.
It is a negative real number.
No, it is not.
It is not the only real number and so there is no answer to the question!
If the coefficient of i is not zero then the number is not real.
