With zero everything in place!

Just think, zero! Nothing and if you think so? If they did not have zero now, there would be no computers, no television, no mobile communication ... no digital technologies! What can I say, we could not multiply two two-digit numbers. Zero is the great invention of humanity and the cornerstone of our numerical system. Zero deserves to talk about him.

The figure "nothing"

The life of the number and the number "zero" began from the moment in which people realized the need to designate the specific number "nothing". Before that, it was considered by the collective mind that if there is nothing, it is not necessary to record anything. But the geniuses of humanity in different parts of the world realized that zero is vital.

And the sages, originally from Hindustan, denoted a zero with the sign of an elongated circle, which is familiar to us.

SourceThe word "Zero" (Zero) came from the Latin "Nulus" - no.

With zero everything in place!

With the arrival of the zero symbol, everything literally took its place. A convenient and practical positional numerical system appeared in which the value of a digit depends on its place in the numerical register, that is, its position.

The use of the zero digit allowed not to introduce new characters to write large numbers. An elegant system of recording any number using only ten digits appeared. Now nobody will confuse the numbers 15, 150, 105 or 15000.

Zero arithmetic properties

Since zero is a number, it has properties. If you add a zero to any number, the number will not change. If you subtract zero from any number, the number will not change (add or subtract, but zero is nothing!).

If zero is multiplied by a number, then we get zero, since we take the number zero times. The zero is divided by any number, we get zero. This is understandable, we divide zero into any number of parts, we get zero!

Now let's try to divide the number by zero. Is it possible to divide the number into zero parts? How, then, of the zero parts to add what we share? To avoid such difficulties, division by zero is forbidden. It is impossible to divide by zero!

Zero - the beginning of the trip

If you drive on a motorway, you will find kilometer posts with marks along the road: 20 km., 30 km. and so on These are signs of the distance from the main post office of the city from which it came out. The main post office of the city is considered the beginning of the trip, its zero mark.

In some cities, the zero marks or the beginning of the road are specially installed signs with the "Start of roads" mark. Kilometer zero). For example, a poster of this type is installed in the center of modern Minsk (the capital of Belarus), in the Plaza of October.

And in the capital of Hungary, Budapest, on the site of kilometer zero, the beginning of all roads, a monument to Zero was erected. This is the only monument to the figure.

The counting of the meridians of the Earth to determine the geographic coordinates is of Greenwich (the first meridian).

Zero - the beginning of time

It is necessary to count the years and the times; otherwise, people would not understand what happened first and then what ...

The beginning of all times ... Where is it? If this beginning is the moment of the origin of the Universe, then the scientists still discuss when it happened ... If it is the moment of the origin of life on Earth, then it is also difficult to decide ...

Then, people agreed on a conditional time principle, linking it to a specific event. As you may have guessed, this event is the Nativity of Christ.

It is Christmas that we consider our time, we are counting our time. We consider Christmas to be the zero point in direct time. Everything before the birth of Christ was before our era; And everything that happened later was in our time.

Each person has their own relationship with zero. But nobody wants to have zero income, zero success, zero relationships and zero knowledge. You can improve your knowledge of mathematics by studying the articles in the Mathematics section of entertainment.

However, zero is not always nothing, if you remember that it is "zero": three or four zeros to the right of any other number in our salary, generates fabulous income for our life.
