Snabb hjälp med c# miniräknare
Hej,
Jag har gjort en miniräknare som första projekt på programmeringen i skolan och den ska vara klar imorgon så jag behöver snabb hjälp av någon som kan se varför det blir ett konstigt tal som jag inte förstår var det kommer ifrån när man trycker på tex 5+5 eller liknande och sen summerar det.
