1 case : Is it possible if I enter in creator 2+2 = {x} then in post _2+2 = 4_ ? Something like that ?

You will have to write a plugin for that.

As a starting point, you can [look](https://github.com/discourse/discourse/tree/c00dab89e47baa582046574e91d6da37616b7a75/plugins/discourse-narrative-bot) at how the discobot rolls 🎲

Sure, you can also use a `post_created` webhook and “patch” the post using an API call if you’re using an external service.
