මේක මේ ම් dp education එකෙ python course 1 එකේ assignment 2 එක. මේකේ තියෙන්නේ history එක display කරන්න. මම ඒක හැදුවා. වැඩේ නම් හරියට වෙනවා. ඒත් මගේ history එකේ answer එක විතරයි පෙන්නන්නේ. මට ඔනේ සම්පූර්න පේලියම පෙන්නන්න. ඒ කිව්වෙ operators and operanands and the result. ඒත් මම කීප විදියකටම ට්ර්යි කලාට හරි ගියේ නෑ. මේක පොඩ්ඩක් බලන්න පුලුවන්ද? මම images and code එක දාලා තියෙනවා.
