Man entschlüsselt am besten zunächst die absoluten Werte der drei Zeilen, dass ergibt {number_1},{number_2} und {number_3}.

\n

Anschließend wählt man die Vorzeichen so, dass $\\var{number_1}+(\\pm\\var{number_2})=\\pm\\var{number_3}$ herauskommt.

\n

Hier ergibt sich $\\var{number_1}+(\\var{no2})=\\var{no3}$ herauskommt.
