If you don't find the math structures you need using the keypads, you can also enter math formatted content directly in LaTex

 

First, enter Math authoring mode by clicking on the square root symbol in the question text area.

Then click on the LaTex Mode in the lower left of the window:

Here is a more complicated example in which a Table is generated:

Unicode

 

In addition, Brahmic, Georgian, Chinese, Japanese, and Korean glyphs are always accepted in text mode. However, these glyphs will be rendered from system fonts so their typography may clash. You can provide rules for CSS classes .latin-fallback, .cyrillic-fallback, .brahmic-fallback, .georgian-fallback, .cjk-fallback, and .hangul-fallback to provide fallback fonts for these languages. Use of these glyphs may cause small vertical alignment issues: We have detailed metrics for listed symbols and most Latin, Greek, and Cyrillic letters, but other accepted glyphs are treated as if they are each as tall as the letter M in the current font.

If the rendering mode is set to strict: false or strict: "warn" (default), then will accept all Unicode letters in both text and math mode. All unrecognized characters will be treated as if they appeared in text mode, and are subject to the same issues of using system fonts and possibly using incorrect vertical alignment.
