Depending on your writing style, everyone has a different appreciation angle.
Generally speaking, it is okay to write the numbers in a way that others can understand them. If you can develop on this basis and want to make the numbers more beautiful, you can try to buy Braille stickers and practice them. There are calligraphy books specifically for practicing numbers. Write more, practice more, and imitate more, and you will be able to write numbers well.
Introduction
Arabic numerals consist of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9***10 counting symbols. Use the place value method, with the high order on the left and the low order on the right, writing from left to right.
With the help of some simple mathematical symbols (decimal point, negative sign, percent sign, etc.), this system can clearly represent all rational numbers. In order to express very large or very small numbers, people created scientific notation based on Arabic numerals.
