Numbers consist of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 * * * 10 counting symbols. Take the position value method, the high position is on the left, the low position is on the right, and the writing is from left to right. With the help of some simple mathematical symbols (decimal point, minus sign, percent sign, etc. ), this system can clearly represent all rational numbers. In order to express extremely large or extremely small numbers, people have created scientific notation on the basis of Arabic numerals.
