Using the "Direct math input" block to insert some equations.
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.
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:
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)
