# Showing a is equivalent to b modulo m

Hello. how do I use libremath to input a b modulo m ? I know I can do a equiv b but I do not know how to add m on top of equiv symbol

I was taught this notation:

`````` a equiv b ~ ["mod" m]
``````

where the modulo constraint is explicitly written at right of the equivalence statement.

However, if you prefer to have m superscript over the equivalence operator, you can:

`````` stack { size 8 m # a equiv b ]
``````

but this is not very nice because you canâ€™t fine-tune the vertical position of m.

Here are both renderings:

PS: when asking on this site, always mention OS name, LO version and save format.

`a equiv csup{m} b`

EDIT: I was just testing.
Now I searched for some Help. I can guess that sup is for superscript, and c is for character (see @ajlittozâ€™s comment below).
The result of `binom mâ‰ˇ` is so so.

thanks @ajlittoz for this but I went with @LeroyGâ€™s solution. thank you @LeroyG as well.

Almost correct. c is for center. You have lsup and rsup variants for positioning superscript at left or right of object. And I didnâ€™t think you could â€śdecorateâ€ť an operator in this way (always thought that super- and subscript applied to variables). Thanks for the tip.
