1 consists of a vertical line and a horizontal line, with the vertical line from top to bottom and the horizontal line from left to right. To determine the position of the number, it is generally to put the number in the center of the paper or slightly to the left. Then, draw a vertical line from top to bottom, with a moderate length, neither too long nor too short. Then, draw a horizontal line from left to right, and the intersection with the vertical line is located in the middle of the horizontal line.

2. When drawing horizontal lines, pay attention to keeping the line thickness consistent, and don't have different thicknesses. Check whether the shape of the number is regular and whether the horizontal and vertical lines intersect vertically. Keep the continuity of strokes and don't break them. Pay attention to the size of the numbers, keep them consistent, and don't have different sizes.

3, in the process of writing, to maintain the stability of the wrist, avoid jitter. After writing, you can gently press the numbers with your fingers to make them more obvious. When writing the number 5, we should pay attention to the order, shape and size of strokes, and keep the consistency and stability of strokes, so as to write the correct and beautiful number 5.

The role of numbers

1, representing quantity and size: Numbers can be used to represent the quantity and size of objects. For example, "5" can represent five apples or five people. This representation is simple and clear, which is convenient for people to calculate and compare. Numbers can also be used to encode and encrypt information, such as passwords and QR codes.

2. Describe time and space: Numbers can also be used to describe time and space. For example, "3. 14" can indicate the value of pi, while 40°C can indicate the temperature of water. This expression can help people better understand and master the laws of nature. It has played an important role in promoting the development and progress of human society.

3. Mathematical operation: Numbers are the basis of mathematics, and various numerical results can be obtained through operations such as addition, subtraction, multiplication and division. These results can be used to solve practical problems, such as calculating commodity prices and predicting future sales. Numbers play an irreplaceable role in modern society and are widely used.
