Is 132 an Arabic number

It can be called Arabic numerals
In the 3rd century AD, an Indian scientist, Bagdad, invented the Arabic numerals
The most ancient counting items are about 3. In order to imagine the number "4", we must add 2 and 2. 5 is 2 + 2 + 1, and the number 3 is 2 + 1. It is probably later that the number 5 is represented by five fingers written by hand and the number 10 by hands is represented by 10. This principle is actually the basis of mathematical calculation. Roman counting only has numbers up to V (i.e. 5), The number within X (i.e. 10) is composed of V (5) and other numbers. X is a combination of two V's. the same number symbol has different quantities according to its position relationship with other digital symbols. Thus, the concept of number position began to emerge. Mathematically, this important contribution should be attributed to the ancient residents of the Lianghe River Basin. Later, the ancient bream people improved on this basis, He invented ten symbols 1,2,3,4,5,6,7,8,9,0 to express numbers, which became the basis of counting today. In the eighth century, the oldest block record with the sign of zero appeared in India
Around 500 A.D., with the rise and development of economy, culture and Buddhism, mathematics in Punjab, the northwestern Indian subcontinent, has always been in a leading position. Astronomer ayobihet has made a new breakthrough in simplifying numbers: he records numbers in a grid, if there is a symbol in the first grid, such as a dot representing 1, Then the same dot in the second grid represents ten, while the dot in the third grid represents 100. In this way, not only the number symbols themselves, but also their position order also have important significance. Later, Indian scholars introduced the symbol of zero. It can be said that these symbols and expressions are the ancestors of today's Arabic numerals
Two hundred years later, the Arabs united under Islam conquered the surrounding nations and established an Arab Empire from India in the East and Africa to Spain in the West. Later, the Islamic Empire was divided into two countries: the East and the West, Among them, the eastern capital, Bagdad, is particularly prosperous. The Greek culture from the West and the Indian culture from the East are all gathered here. The Arabs understand and digest the two cultures, thus creating a unique Arab culture
About 700 years ago, the Arabs conquered the Punjab area. They were surprised to find that the mathematics of the conquered area was better than them. So they managed to absorb these figures
In 771, the mathematicians in northern India were caught in Bagdad, Arabia, and were forced to teach the local people new mathematical symbols and systems, as well as the calculation method of Indian style (i.e. the calculation method currently used). Because Indian numbers and Indian counting methods are simple and convenient, and their advantages far exceed other calculation methods, Arab scholars are willing to learn these advanced knowledge, Businessmen are also happy to do business in this way
Later, the Arabic introduced these numbers to Spain. In the 10th century, it was spread to other European countries by Pope Gerber oriyak. Around 1200 A.D., European scholars formally adopted these symbols and systems. In the 13th century, under the advocacy of the mathematician fevanacci of Pisa, Italy, ordinary Europeans began to use Arabic numerals, In the 15th century, this phenomenon was quite common. At that time, the shape of Arabic numerals was not exactly the same as modern Arabic numerals, but rather close to them. Many mathematicians spent a lot of effort to make them become the writing style of today's 1,2,3,4,5,6,7,8,9,0
Arabic numerals originated in India, but they were transmitted to all directions through Arabs

The Arabic numerals were invented by Indians______ (judge right or wrong)

Arabic numerals were invented by ancient Indians and spread from Arabs to Europe, so they are called Arabic numerals,
So the statement in the title is correct
So the answer is: √

Why are the numbers invented by Indians called Arabic numerals

About the third century BC, the ancient Indians finally completed the invention and creation of the number symbols 1 to 9, but there was no "0". 0 appeared in the Gupta Dynasty more than 1000 years after the invention of the number symbols from 1 to 9

Write the numbers of the following patterns (the same pattern represents the same Arabic numerals) O= △= O - ☆ = △ ☆= ◇= - + × (the square can't be changed into diamond) = = = △ × ◇ =

Because △×} = 8 can have, 1 × 8 = 8, 2 × 4 = 8, 4 × 2 = 8, 8 × 1 = 8, but o - → = △, × + o = ∞ therefore, △ <} therefore, the conditions are as follows: 1 × 8 = 8, 2 × 4 = 8, when △ = 1, ∞ = 8, O - ∞ = 1, O + ∞ = 8, then o = 4.5, × = 3.5

How many pictures are there in five characters in Arabic numerals How many Chinese characters are there in Arabic numerals

How to draw with Arabic numerals? Primary school mathematics teacher asked to draw numbers

Use 3 to draw ears, 0 to draw face, 2 to draw nose, 4 to draw left eye, 5 to draw right eye and eyebrow, three petal mouth, 1 and 7 to draw neck, 6 and 9 to draw body
0,1,2,3,4,5,6,7,8,9 can be drawn as a rabbit

Write the numbers of the following patterns (the same pattern represents the same Arabic numerals) ☆= ◇= ☆—△= ◇ — + × △= ※= △＋☆=※ = 　= = ◇× ※= 8

☆=3 ◇=2
△=1 ※=4
It should be, - + × = ==

There were no Arabic numerals in ancient China,

In fact, there are different calculation methods for vertical chips
