Как заставить случайных операторов работать в математической программе

0 голосов
/ 21 июня 2019

У меня есть математическая программа, которая запрашивает случайные числа умножения, поэтому я хотел сделать это со случайными операторами, проблема состоит в том, что выбор оператора дает мне ноль, а деление дает мне дробные числа.

То, что я пробовал, было частью кода, который я обнаружил в сети, затем я попытался сделать это с метками, но сумма не считала бы текст метки как оператор, даже если я попробовал строковое значение и CInt, я попробовал это с текстовыми полями, надеясь, что это будет читать из этого. Не сработало Смотрел кучу видео на YouTube. Это не сработало. Случайный выбор оператора работает сам по себе, но дает некоторые ответы на некоторые вопросы в части деления

Вот весь мой код, который я пытаюсь работать со случайным оператором и делением, чтобы дать правильные ответы без дроби. Я не очень хорош в этом, но пытаюсь улучшить. Спасибо за ваше терпение.
