About Modifiers
Modifiers are special terms that you can use to modify the behavior of keywords. For example, you can use the modifier real after the keyword assume to require that a variable be a real number.
The available modifiers and their corresponding valid keywords are listed below:

Special Modifiers
You can use the modifiers fully and using as standalone keywords without adding a preceding keyword. You can use any valid combination of keywords and modifiers by adding a comma between the keyword and the modifier. You can also press Shift+Enter and add the same modifier on the next line.
