1. Draw a grid with a straight line: draw a grid with a ruler in a math book to ensure that the layout of mathematical symbols or graphics is neat and readable.
2. Smooth strokes: When writing numbers or symbols, the strokes should be smooth to avoid shaking or trembling, so that the written numbers or symbols will be clear.
3, the letters should be unified: when writing letters, we should pay attention to the consistency of case, thickness and inclination, which can make the whole math book more beautiful.
4. Make good use of space: In the process of writing, make full use of space to avoid too crowded or too empty typesetting.
5. Mathematical formulas should be standardized: when writing mathematical formulas, we should follow the standardized format, such as using correct symbols, brackets and subscripts. To make the formula easier to read.
