Rich Text Format (RTF) supports some math symbols, but its capabilities are limited, particularly in rendering complex equations. While RTF allows for features like subscript and superscript, it lacks robust math support. LaTeX is recommended for composing mathematical equations due to its superior rendering capabilities. Alternatives such as HTML and PDF can handle UTF/Unicode character sets, but they do not match LaTeX's ability to present intricate mathematical expressions effectively. For basic math symbols, a Unicode keyboard can be used, but its rendering is also limited.
