1. Use Arabic numerals: In mathematics, Arabic numerals are usually used to represent numerical values. Arabic numerals include 0, 1, 2, 3, etc. They are concise and easy to understand and calculate.
2. Maintain the continuity of numbers: When writing numbers, keep the continuity of numbers, that is, don't interrupt the writing of numbers. For example, it should be written as 123 instead of 123.
3. Use appropriate unit symbols: When representing numerical values, use appropriate unit symbols to represent numerical units. Such as meters (m), kilograms (kg) and so on.
4. Use the correct decimal point position: When writing decimals, use the correct decimal point position. The decimal point should be in the middle of the number, not at the end. For example, it should be written as "0.5" instead of "0.5".
5. Use parentheses and exponential symbols: When complex mathematical expressions are involved, parentheses and exponential symbols can be used to clearly indicate the operation order and power relationship. For example, it should be written as "2 3" instead of "2 to the third power".
6. Use appropriate symbols and abbreviations: In mathematics, there are some specific symbols and abbreviations used to represent specific mathematical concepts or operations. Such as plus sign (+), minus sign (-), multiplication sign (×), division sign () and so on.
7. Use clear fonts and font sizes: In order to ensure the readability of numbers, you should use clear fonts and appropriate font sizes to write numbers. Avoid using fonts that are too small or too large to avoid reading difficulties.
In short, digital writing in mathematics should follow the principles of clarity, accuracy and standardization to ensure the correct communication and understanding of mathematical concepts and calculation processes.
