The

Arithmetical Hierarchyis an example where one in mathematics uses aligned subscripts and superscripts. When writing in Latex I e.g. write $\Pi^1_1$ to talk about a certain class of formulas. How can I achieve this in Word or LibreOffice?

**Answer**

Yes it’s certainly possible with LibreOffice.

In LibreOffice Writer, click `Insert`

> `Object`

> `Formula`

In the window that opens at the bottom type in the formula as follows

```
%PI^1_1
```

LibreOffice also comes with a separate Math application, which can also be used to create formulas. There’s further documentation here on the using formulas in Math in LibreOffice https://wiki.documentfoundation.org/images/3/37/MG40-MathGuide.pdf
