Recently, I started to use Github Page to write a summary on a course that I followed on Edx about Statistics. I am using **Jekyll** to create static websites. In order to insert lots of math equations, I am using **Mathjax**.

You can add these scripts in the **head** to import Mathjax:

```
<script src="https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML" type="text/javascript"></script>
<script type="text/x-mathjax-config">
MathJax.Hub.Config({
tex2jax: {
skipTags: ['script', 'noscript', 'style', 'textarea', 'pre'],
inlineMath: [['$','$']]
}
});
</script>
```

By doing so, you can show most of the math functions correctly, except for some **inlineMath**: math between two $ signs.

what you want to show | what web shows |
---|---|

$\vert x \vert$ | seperation of table column |

$\{1\}$ | ${1}$ (no “{}”) |

$(X)_{0}+X_{1}$ | $(X){0}+X{1}$ (`<em>` tags) |

Solutions:

what you want to show | What you should enter |
---|---|

`|` |
`\vert` |

`{` |
`\\{` |

`}` |
`\\}` |

`)_` (underscore) |
`)\_` or add a space between `)` and `_` |

`_(` (underscore) |
`\_(` or add a space between `_` and `(` |

`}_` (underscore) |
`}\_` or add a space between `}` and `_` |

`_{` (underscore) |
`\_{` or add a space between `_` and `{` |

more than 1 * in the paragraphe | `\*` |

$\Leftrightarrow$ | `\Leftrightarrow` (not `\Harr` ) |

$\arg\max$ | `\arg\max` (not `\argmax` ) |

2 `{` together |
`{ {` (add a space between them) |
