Why zero is important

Zero is the smallest number non-negative integer the immediately precedes 1. It cannot be termed as a positive or a negative number. The correct way of describing zero would be a number which equals to cardinality or an amount of null size. It also falls under the category of complex and algebraic numbers.

In the 21st century, zero is so common that to talk about it seems like much ado about nothing. Zero is important if you think about sets. An empty or void or null set is one which has no element or member.

The addition property of zero: Whenever Zero is added to a whole number or vice-versa, the sum will be a whole number. The subtraction property: Whenever zero is subtracted from a whole number the difference will be the whole number and whenever a whole number is subtracted from itself, the difference will be zero. The multiplication property: It is a little like addition property in that it does not matter in what order you do the operation to the whole number.

Thus, a whole number multiplied by zero is equal to zero and vice-versa. Zero is very important for its place-holding value. If you have a number like three hundred five, how do you write it so, that you understand that there are no tens in the number. You cannot write it as 35 because it is a totally different number Two-digits-number.
