Hey @Dionisis_Priftis,

welcome to Airtable community.

You your case you have to extract the numerical info from long text fields and then use the exports in formula calculation.

I hoe my response helped you and for any deeper support please feel free to text at any time.

Yours sincerely,

Dimitris Goudis

@Dionisis_Priftis Airtable doesn’t offer an “Evaluate” function like other programming languages do, so I don’t think there’s any way that you could do that natively with an Airtable formula, unless all of your mathematical expressions are always going to look similar to that one — with a single known operator in between 2 values.

Although perhaps you could do something with Regex or a custom script.
