The modern system of counting or where invented Arabic numerals

Today math is hard to imagine without the use of figures and numbers.Initially, the math used Roman numerals, which were 14 and which were not zero, but it soon became figures depicted in the form of letters, as in many nations they had a hidden meaning.With the introduction of Arabic numbers, in mathematics there was zero.Now, many people are wondering where invented Arabic numerals.The answer to this question must be sought among historians.

word "figure" is of Arabic origin and means "zero."In India, the inscription was discovered wall, where there was number 270, this inscription refers to the I century and is the first testimony of the use of numbers.Already in the V century, the Indians had set out the decimal system, and a century later, they freely operate this system, as well as the concept of "zero", which stands for "nothing" or "empty."By this time, most of the nations of the world had its own system of accounts, however, only in India use zero.For the first time in India scholar Mohammed

Al Khwarizmi used system of writing numbers with zero, this fact has encouraged the Indian system of figures around the world.

considering the question of who invented the Arabic numerals, you can see that Arab mathematicians were slightly modified Indian figures in order to fit under their letter.Thus, the Arab people became the first people who met with the Indian system of calculation.This is not surprising, because at that time in India was invented by a system in which the number of recorded stairs.These steps were a few more than the numbers, which is why calling a large number, the name of the stage had to be called after each digit.This caused some inconvenience, so the Indians soon began to call all numbers without names of a large number of steps.

In India, where invented Arabic numerals, digital steps used for a long time.If the number of missing one of the steps, the Indians instead of its title says "empty."On paper, the word "empty" Indians first set point, and later - a circle.And there was a zero.

This way of writing numbers, submitted by India, is convenient for the different estimates, so the whole world now enjoys it.Thus, India may be considered the country where invented Arabic numerals and the decimal system of the account numbers.

It would seem that with the invention of numbers and decimal counting system, were to appear the first few hours.But we know that more than three thousand years ago in Babylon used the first few hours, they represented the dial has twelve divisions around the edges and in the center of the rod.These watches were sunny, so when you move the sun in the sky, the shadow rod fell on the appropriate number on the dial.These clocks were used in the daytime, when it is dark they replaced water clock, represents the earthen vessel with water flowing from it, one drop.The vessel was divided by walls, however, when the water level drops, it is possible to see at what fission she stopped so determined that hour.In Europe, the clock was in the form of candles graduated.About the one who invented the mechanical clock, historians argue to this day, some argue that it was Patsifikus others - Herbert.In any case, the clock appeared before the invention of Hindu figures previously had dial division with images of zodiac signs, and later on the dial portrayed characters and symbols.After some time, it began to be used the Roman numerals on the watch dial.

Thus, today known , where invented Arabic numerals.Invented in India, people use the system account for many centuries, and it reached up to our time, and is used today.
