The unique nonnegative square root of a nonnegative real number. For example, the principal square root of 9 is 3, although both -3 and 3 are square roots of 9.
An integer is a whole number. Nonnegative mean not negative. A nonnegative integer is a whole number that is not a negative number. For example, 0, 1, 2, 3, 4, 5,....
The first four consecutive nonnegative integers. One-hundred and twenty-three with a leading zero.
A non-zero real number! In set notation, it may be represented as R \ {0}.
No. Not if the second number is zero.
Saying "positive" means "greater than zero". Saying "non-negative" is a shortcut to saying "greater than or equal to zero".
The unique nonnegative square root of a nonnegative real number. For example, the principal square root of 9 is 3, although both -3 and 3 are square roots of 9.
Non-negative includes zero, positive does not.
x > 0 x is greater than zero.
The absolute value of a number is always nonnegative.
An integer is a whole number. Nonnegative mean not negative. A nonnegative integer is a whole number that is not a negative number. For example, 0, 1, 2, 3, 4, 5,....
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.
No. It is nonnegative. Zero is neither positive nor negative.
The absolute value of a number is the distance that number is from zero. 2 and -2 are both the same distance from 0, they are 2 away. Therefore, |-2| = 2, and |2| = 2.
not a real number * * * * * Zero is very much a real number. In fact it is the additive identity for the set of real numbers.
