First, the numbers should be written separately, not Lian Bi; 6, 8, 9, 0, write as round as possible.
Second, try to keep all the numbers tilted about 45 degrees to the right.
Three, the height of the number should be one-half to two-thirds of the height of the account book table. Among them, 6 is higher than other figures, but generally does not exceed the table; 7 and 9 are slightly lower than other figures, and the lower part accounts for about one-third of the upper part of the next line.
Fourth, there should be no gaps when writing 0, 8 and 9, and the circle should be sealed; The two perpendicular lines of 4 should be obliquely parallel and cannot be connected; When writing 2, you can't write it as a "Z", but draw a circle on the lower corner.
Digital introduction:
There are several kinds of numbers, and Arabic numerals are the most common one. Arabic numerals were not invented by Arabs, but by Indians. In fact, it should be listed as Hindi, but it spread to Arabia first and then to the world, so it is called Arabic numerals. Numbers are written symbols used to represent numbers. Different counting systems can use the same number.
Digital history:
Around 500 AD, with the rise and development of economy, culture and Buddhism, Punjab in the northwest of Indian subcontinent has been in a leading position in mathematics, which originated in India. Astronomer Ayepihite made a new breakthrough in simplifying numbers: he recorded numbers in a grid, if there were symbols in the first grid, such as the point representing 1.
Then the same point in the second cell means ten and the point in the third cell means one hundred. In this way, not only the digital symbols themselves, but also their position order is of great significance. Indian scholars also introduced the symbol zero. It can be said that these symbols and representations are the old ancestors of Arabic numerals today.
Digital source:
Westerners call these numbers Arabic numerals because they first came into contact with Arabs and used these data, mistakenly thinking that they invented them, which has caused this historical misunderstanding. Later, with the wide spread in the world, everyone agreed with the Arabic numerals.
