The number 1: Don't write straight, it's oblique, but not too oblique. Don't understand it as a connection between two diagonal corners, but the pen is not closed in the upper right corner until the lower left corner.

Number 2: It looks like a duckling sitting on the ground, but pay attention to it, with a round head and a flat body. The horizontal stroke of the pen should be written from the lower left corner to the lower right corner without stopping.

Number 3: It looks like a combination of two ears, but notice the ratio of the upper part to the lower part, and the size is 4:6. The head and 2 are written in the same way and should be rounded. When the upper ear is finished, write the ear slowly, not quickly, so as not to form a circle when handing over.

Number 4: The key is to master two kinds of vertical pens, both of which should be written obliquely. The first vertical is more oblique and longer than the second vertical, and the horizontal should be crossed out at the lower half of the Japanese font.

Number 5: Like 4, the vertical pen should be inclined, just 70-80 degrees. Come to the upper left corner and draw a semicircle on the center line, and see the connection of the last horizontal line.

Number 6: The starting position of the pen is less than the midpoint of the upper boundary, which is a line with a little radian, and then draw a circle in the lower grid to collect the pen.

Number 7: just pay attention to the pen at the midpoint of the bottom line, and the vertical line is slightly inclined.

Number 8: Of all the numbers, this number is not easy to write, and it is really ugly. It is not made up of two circles, but an S and an inclined vertical line. On the whole, it is small and big. Therefore, when writing a circle, you should turn the lower part of the circle without touching the left line, then touch the bottom line, and then reach the pen obliquely. Be careful not to touch the pen circle.

Number 9: Pay attention to the starting point in the upper right corner, draw a circle, occupy the upper part of the grid, return to the starting point, tilt vertically, and close the pen to the left at the midpoint of the lower edge.

The number 0: It can be said to be like an inclined egg. Start from the top right corner and write diagonally. Write flat and the arc should be as round as possible.

Arabic numerals (also called Indian numerals) consist of ten counting symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 * *. Arabic numerals were first invented by ancient Indians, then spread to Europe by Arabs, and then modernized by Europeans. People think it was invented by Arabs, so people call it "Arabic numerals".

Origin:

Around 500 A.D., with the rise and development of economy and caste system, Punjab in the northwest of Indian subcontinent has been in a leading position in mathematics. Astronomer Ayepihite made a new breakthrough in simplifying numbers: he recorded the numbers in a grid, if there were symbols in the first grid.

For example, a point represents 1, then the same point in the second cell represents ten, and the point in the third cell 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.

Evolution:

Around 2500 BC, an inscription notation called halaba number appeared in ancient India. Before and after A.D., there were two kinds of figures: karoshi figures and Brahman figures.

In the 3rd century AD, the Indian scientist Baghdad invented Arabic numerals. After the 4th century AD, the symbol of zero in Arabic numerals became increasingly clear, which made the notation gradually develop into decimal system, such as Dwinnaghli numerals which appeared after the 8th century AD. ..

Around the 9th century AD, Indian numerals were introduced into Arabia, and two kinds of Arabic numerals were derived from the original Brahman numerals: East Arabic numerals used by Middle Eastern Arabs and West Arabic numerals used by Spanish Arabs. The Arabic numerals in the East are very similar to the forms used by Arabs, and the Arabic numerals in the West later developed into the forms widely used by us.
