Mathematical symbols are a wonderful way of expressing your mathematical ideas. However, your text is intended for a human reader, so clearer, easier-to-read language is better.

• Use symbols for logic statements.
• Use symbols if it is cumbersome to express your ideas in words.
•  Use words if it is not much longer than using symbols.
• Symbols should be separated by words or punctuation marks.
