Висновок
В моїй розрахунковій роботі було представлено приклад калькулятора, що перемножує числа. Було представлено побудову діаграм UML, розглянуто деякі типи діаграм та їх значення, структуру, на зворот ньому процесі до проектування було продемонстровано переваги попереднього проектування розроблюваного даного програмного продукту.
