      - Var "{b}" => values from -5 to -2 
      
      - Formula "{{a}}" => {b}-{b}+{b}

      Description

      As mentioned in SAK-38435, the syntax

      {x}-{x}

      doesn't work for calculated questions if x is negative. It ends up being 1-1 and mxParser throws and error. It's mentioned here that this "may" be fixed even though this issue is particular issue is closed. It looks like we could work around it but better for them to fix it.
