Zero is a an integer and, since all integers are real numbers, zero is a real number.
It is a negative real number.
Zero is the additive identity in the set of real numbers; when you add zero to any number, the number does not change its identity.
no because zero isn't positive or negative it is neutral
The sum is zero.
You can invert almost any number by dividing 1 by that number. Zero is an exception since division by zero yields the equivalent of infinity, which is difficult to deal with by the usual rules of arithmetic. We cannot really know what the product of zero and infinity is. All other real numbers can be inverted.
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.
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.
It is a negative real number.
yes.
Zero
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.
no
Zero is a real number, it is neither positive or negative, and it is even.
A non-zero real number! In set notation, it may be represented as R \ {0}.
Yes, zero is a real number. If you can plot it on a number line, it is real. It is also an integer, a whole number, a rational number, and could probably be designated as a few other types of numbers.
