A short story about the origin of numbers

The story of the origin of numbers is as follows:

Around 500 AD, with the rise and development of economy and caste system, Bai's mathematics was in a leading position in Punjab in the northwest of Indian subcontinent. Astronomer Ayepihite made a new breakthrough in simplifying numbers: he recorded the numbers with a grid. If there is a symbol in the first grid, such as a point representing 1, then the same point in the second grid represents ten, and the point in the third grid represents one hundred.

In this way, not only the digital symbols themselves, but also their position order is of great significance. Later, Indian scholars introduced the symbol zero. It can be said that these symbols and representations are the old ancestors of Arabic numerals. This principle is actually the basis of mathematical calculation. Rome's count is only numbers within V (that is, 5), and numbers within X (that is, 10) are composed of V (5) and other numbers.

ⅹ is a combination of two ⅴ, and the same digital symbol has different quantities according to its position relationship with other digital symbols. In this way, the concept of digital position began, and this important contribution in mathematics should be attributed to the ancient residents of the two river basins. Later, the ancients improved on this basis and invented the symbols 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 to represent numbers, which became the basis of counting. In the eighth century, the oldest zero-symbol engraving record appeared in India. At that time, zero was the first.

When Arabic numerals are used:

1, physical value. Physical quantities must use Arabic numerals, and the units of measurement after the numerals must use Chinese legal units of measurement.

2. Century, year, year, month, day and time.

3. The number before the counting unit. Numbers greater than 10 before the counting unit must use Arabic numerals, integer 1~ 10, and Arabic numerals should also be used where appropriate.

4. The number of counts. Whether it is a chart or a narrative, the counted figures must be Arabic numerals, including integers, decimals, percentages, proportions, etc.

5, model, number, serial number, code, etc. Instrument model, sample number, standard number, etc. Often appear in scientific papers, Arabic numerals should be used, and the word "first" is often used before ordinal numbers.
