## Who invented 0 in India?

AryabhataWhat is widely found in textbooks in India is that a mathematician and astronomer, Aryabhata, in the 5th century used zero as a placeholder and in algorithms for finding square roots and cube roots in his Sanskrit treatises.

## What is the opposite of 0?

negativeThe opposite of a positive number is negative, and the opposite of a negative number is positive. Since the opposite of 0 is 0 (which is neither positive nor negative), then 0 = 0. The number 0 is the only number that is its own opposite. Whole numbers and the opposites of those numbers are all integers.

## Is there such thing as negative infinity?

## Is negative zero a real number?

Therefore, the “negative” of zero is just zero, since 0+0=0.

## Is 0 considered a number?

0 (zero) is a number, and the numerical digit used to represent that number in numerals. It fulfills a central role in mathematics as the additive identity of the integers, real numbers, and many other algebraic structures. As a digit, 0 is used as a placeholder in place value systems.

## Can there be a negative 0?

There is a negative 0, it just happens to be equal to the normal zero. For each real number a, we have a number −a such that a+(−a)=0. So for 0, we have 0+(−0)=0. … So −0=0 be canceling the 0 on the left hand side.
