Description
Type complex math expressions easily into your wordpress page using MathQuill (http://mathquill.com/). This plugin adds a new block editor called ‘Direct math input’ in the ‘widgets’ category.
Math expressions are saved in LaTeX format and rendered by MathQuill during pageview.
Usage
After installing, a new block editor called ‘Direct math input’ will be available. Each block contains a MathQuill instance
where you can edit math right on your page.
When the math editor is focused, you can enter math symbols using your keyboard or via copy/paste.
See the http://mathquill.com/ homepage for a visual demonstration of how to input math.
Some common keyboard shortcuts are as follows:
 / (forward slash) Enter a new fraction, with focusable input areas for numerator and denominator
 ^ (caret) Enter a new superscript, e.g. to add an exponent
 _ (underscore) Enter a new subscript
 ( (open parentheses) Open parentheses (which will scale based on the height of the content inside) Other parenthesis types behave similarly, e.g. [ and {
 \ (backslash) Start typing one of the control sequences below. When finished, press enter or space to see the resulting symbol
Control sequences – to create each symbol, type the full sequence (including the backslash) into the math editor, followed by
space or enter. (not an exhaustive list)
