# Who introduced zero?

It is believed that the zero or 'cypher' was unknown in ancient times - as an example, in the Roman counting system (using I for 1, V for 5, X for 10, L for 50, C for 100, D for 500 and M for 1000) there was no symbol for zero and their method of using letters made any arithmetical calculation very difficult if not impossible.

It is widely believed that the Arabs (possibly around the
Iran/Iraq area) from whom we took our numerical system (1,2,3 etc)
based on 10s, invented the zero as a placemarker so that after
counting 1,2,3,4,5,6,7,8,9 then the first ten would be made by
placing a 1 to the left, with a place marker suggestiing that this
1 represented 'ten' rather than 'one'. This place marker became the
zero. Similarly, in counting tens, after the *ninth* ten the
tenth ten would be represented by *another* 1 placed further
to the left again, and a second place marker - a second zero,
inserted to show that this '1' did not mean '1', nor 'ten ones',
nor '1 ten', but *'ten tens'*. From this system we now have
the system of '1' being one, '10' being 'ten'' and '100' being a
hundred. Unlike the *Roman* system where the largest number
symbol was M for 1000 , this meant that an *infinite* number
of place markers could be inserted so that counting could go on for
ever, using the same system. Also, unlike the Roman system, by
placing numbers diirectly underneath each other, addition and
subtraction (and other processes) could be completed easily as each
column formed contained the same type of number ('1's, '10's,
'100's etc) and there could be added or subtracted much more
easily.

It can be argued then that modern mathematics - the tool from which the theoretical processes leading to the understanding and development microelectronics, space travel, medicine, economics, and so on - would never have developed without the modern counting system. So, with regard to the invention of the zero, we have a great deal to thank the Arabic people for.

### Whwn was Zero introduced to the world?

A2. The need for a zero long preceded its use. We seem to have independent invention of the (modern) use in some written form :- China 400 BCE, Maya 36 BCE, India 458 CE, Western world probably not much before the 12th century CE. Fibonacci - he of the series - introduced the concept in its modern sense to the West about 1200 CE. Questions you should consider include a) is zero a number, b)…

### What is the depreciation schedule of Bitcoin?

The Bitcoin (more commonly spelled as bitcoin) unit of currency will depreciate to zero in 2140. The currency was introduced in 2009 and the each time there is an update the number that are introduced to the system is reduced. It is estimated that when the currency is maxed out in 131 years there will be 21,000,000.00 in cyber circulation.

### What is the smallest one digit natural number?

It is either "1" or "0". There is a philosophical dispute among mathematicians as to whether the number zero counts as a natural number. I think the Phoenicians introduced the concept of zero in written numbers, but even before them, there was always a natural concept of "one apple" and "no apple." Therefore, I'd argue that the smallest one digit natural number is zero.

### Who invented the digit zero?

Zero was introduced initially, not as a number to be used in computation, but as a position marker to distinguish between such numbers as 123, 1203, 1230, and 1023. The Maya, about the 1st century ad, used a small oval containing an inner arc to denote zero. About five centuries later the Hindus began to use a circle or a dot as a symbol for zero; the dot later fell into disuse. These Indian mathematicians…

### InWhich year the symbol 0 is introduced?

Although the origin of zero is controversial, some historians believe that it was invented by the Babylonians in about 500 BCE. In the sixth century, it was discovered by the Hindus and Chinese, and 700 years later, it reached the Western world via the Arabs. Zero is the only integer (whole number) that is neither positive nor negative. In a sense, zero makes negative numbers possible, as a negative number added to its positive counterpart…
