# What makes 0 so special?

## What makes 0 so special?

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.

### What is the story behind 0?

The first modern equivalent of numeral zero comes from a Hindu astronomer and mathematician Brahmagupta in 628. His symbol to depict the numeral was a dot underneath a number. He also wrote standard rules for reaching zero through addition and subtraction and the results of operations that include the digit.

What is the purpose of 0?

As a number, zero means nothing—an absence of other values. It plays a central role in mathematics as the identity element of the integers, real numbers, and many other algebraic structures. As a digit, zero is used as a placeholder in place value systems. Historically, it was the last digit to come into use.

Why is zero the most important number?

Zero is the smallest number non-negative integer the immediately precedes 1. It is an even number as it as it is divisible by 2 with the remainder itself 0 { 0 ≡ 0 (mod 2)} i.e. no remainder . It cannot be termed as a positive or a negative number.

## What would happen without 0?

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!

### What would happen if zero was not invented?

Is zero an even number?

When 0 is divided by 2, the resulting quotient turns out to also be 0—an integer, thereby classifying it as an even number. Though many are quick to denounce zero as not a number at all, some quick arithmetic clears up the confusion surrounding the number, an even number at that.

Is ∞ a real number?

Infinity is a “real” and useful concept. However, infinity is not a member of the mathematically defined set of “real numbers” and, therefore, it is not a number on the real number line.

## Who invented 0 for kids?

Zero was invented independently by the Babylonians, Mayans and Indians . Though ancient civilizations already knew the concept of ‘nothing,’ they did not have a symbol or letter for it.

### Is there an end to infinity?

Infinity has no end So don’t think like that (it just hurts your brain!). Just think “endless”, or “boundless”. If there is no reason something should stop, then it is infinite.

Is infinity possible?

Although the concept of infinity has a mathematical basis, we have yet to perform an experiment that yields an infinite result. Even in maths, the idea that something could have no limit is paradoxical. For example, there is no largest counting number nor is there a biggest odd or even number.
