Real numbers are mainly classified into rational and irrational numbers. Rational numbers include all integers and fractions. All negative integers and whole numbers make up the set of integers. Whole numbers comprise of all natural numbers and zero.

Is 0 a Natural Number? Zero does not have a positive or negative value. Since all the natural numbers are positive integers, hence we cannot say zero is a natural number. Although zero is called a whole number.

Main types ): The counting numbers {1, 2, 3.} are commonly called natural numbers; however, other definitions include 0, so that the non-negative integers {0, 1, 2, 3.} are also called natural numbers. Natural numbers including 0 are also called whole numbers. They can be positive, negative, or zero.

I think the answer is C. Zero.

Zero is an even number because it is divisible by 2 with no remainder. 0 is neither positive nor negative, or both positive and negative. Many definitions include 0 as a natural number, in which case it is the only natural number that is not positive.

Without zero there would be: No algebra, no arithmetic, no decimal, no accounts, no physical quantity to measure, no boundary between negative and positive numbers and most importantly- no computers!

The multiplication property of zero: Regardless of what the other number is, multiplying by zero always results in an answer of zero. Any two numbers whose sum is zero are additive inverses of one another.
