## ZERO – A VALUE WITHOUT VALUE

Introduction

The era when the main era of The Middle Age started was also referred to as the ‘golden age’ from the timeline after the 500BCE. The timeline from 500-1500 changed many things in the world of math and these helped the concept of mathematics to study in greater detail. The one thing which started the era with a strong invention is Zero (0).

Progress of zero

Any method used for counting numbers reaches a point where at some point it becomes positional. All of the positional values reach a point where it symbolizes ” nothing exists here “. Most of the scholars suggested that O was utilized as when the counter was removed it was only shaped which was not used yet. An abax, a table, or a board covered in the sand were the instrument utilized by Greeks for counting purposes.

Brahmagupta

Scholar Born in 598 CE, has a versatile personality. He was well versed in math and astronomy.  Brahmagupta lived in Bhillamala, a place located in Northern India well-known learning center. Brahmagupta was the founder of the invention of rules for the calculation of zero. Initially, zero was defined by Brahmagupta as a result of subtracting any number from itself for example 5-5 =0. Here happened the establishment of zero as a number in its own right simply opposite to figurative notation or placeholder. Brahmagupta also experimented by subtracting zero from a negative number, the result remains unchanged. Also, zero was subtracted from a positive number, the result was the same number. Similarly, zero was added to a positive and negative number, and the same number was found as a result.

Multiplying and dividing rules

When it came to the multiplication and division of numbers with zero there was no clear idea of how can it work. To value it Brahmagupta went to examine the relation of zero after multiplying and describing how the product of multiplying any number with zero is zero, including zero multiplying to zero. The next that came was to explain division by zero where it was problematic to conclude with a solution. Recording the result of dividing a number, n, by zero as n/0. He suggested that a number is unchanged when it is divided by zero.

Conclusion

Mathematics without zero results in too many of the articles in this book that could not have been written where there would be no negative numbers, no coordinate systems, no binary systems no decimals, and no calculus because it would not be possible to describe infinitesimally small quantities. Advances in engineering would have been severely restricted without this great invention. Zero is perhaps the most important number of all. Without this, it was impossible even to count on the currencies. The zero with no value adds value to a number when added after the number. Just think about the situation when the zero was even not defined or even not present in this world.
