Numbers
Here are three basic rules for using numbers in writing, which are quite helpful.

====** Rule 1. Spell out numbers that take no more than two words. O therwise, use the Arabic numerals. **==== ====b) Only seven students came to class today. ==== ====c) Thirty-five is an odd number. ==== ===**Rule 2. Numbers are often used to show dates, times, percentages, addresses and so on. **=== ====b) Xiamen University was founded in 1921 by Tan Kah Kee, a well-known overseas Chinese and also a patriotic leader. ==== ====c) The flight from Boston is due at 15:30. ==== ====**Rule 3. When you are using several nunbers at the same time, they have to be consistent with each other. **====
 * E.g. a) The chef has a file of 365 recipes.
 * ====E.g. a) I went to bed at 11 p.m. last night so I felt extremely sleepy this morning. ====
