## What is the first number 1 or 0?

In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0.

## What is the first number of 0?

Zero (0) is used as a number and also as the numerical digit. Zero gives the additive identity of the integers, real numbers, and many algebraic structures. It is used as a placeholder for writing numbers. Natural numbers start from 1, then 2 and so on.

**Who 1st invented zero?**

Brahmagupta

“Zero and its operation are first defined by [Hindu astronomer and mathematician] Brahmagupta in 628,” said Gobets. He developed a symbol for zero: a dot underneath numbers.

### Where is the first 0 in pi?

The first zero in pi occurs at position 32. What is the probability of a digit not occurring in 32 or greater randomly chosen digits?

### Is zero a real number?

Real numbers can be positive or negative, and include the number zero. They are called real numbers because they are not imaginary, which is a different system of numbers. Imaginary numbers are numbers that cannot be quantified, like the square root of -1.

**Is 0 a digit number?**

Zero has no digits. Consider the lowest n-digit number (where n is natural and n≥1), that is 10n−1 .

## Is 01 and 1 the same?

There is no difference between the numbers 01 and 1 . They are absolutely identical.

## Is aryabhatta invented zero?

Aryabhatta invented zero that means he thought that some number like zero exists and one can represent Ten as Symbol of one as ten digit and Symbol of zero as unit digit. This was firstly added in Bakhshali Manuscript and then it was added in other Lipis. Brahmagupta also deserves some credit for invention of zero.

**Who invented 1?**

Hindu-Arabic numerals, set of 10 symbols—1, 2, 3, 4, 5, 6, 7, 8, 9, 0—that represent numbers in the decimal number system. They originated in India in the 6th or 7th century and were introduced to Europe through the writings of Middle Eastern mathematicians, especially al-Khwarizmi and al-Kindi, about the 12th century.

### Do numbers end?

The sequence of natural numbers never ends, and is infinite. OK, 1/3 is a finite number (it is not infinite). There’s no reason why the 3s should ever stop: they repeat infinitely. So, when we see a number like “0.999…” (i.e. a decimal number with an infinite series of 9s), there is no end to the number of 9s.
