FYI

I changed your code so it formats correctly.

Instead of using the quote button `"` which puts a `>`at the start of each line, use the preformatted text button `</>` which bookends the selected text with `````.

```
```
resolve(N,N) :- integer(N), !.
```
```

which renders as

```prolog
resolve(N,N) :- integer(N), !.

```

NB The default programming language for preformatted text is Prolog, you can also manually chose another language that is configured for this site, see [Language highlighting](https://swi-prolog.discourse.group/t/language-highlighting/2260)

Don’t worry many new users are not aware of these features. 🙂
