создать калькулятор с графическим интерфейсом Powershell

Привет, ребята, я пытаюсь создать калькулятор. Пока что у меня есть графический интерфейс. Но мне нужна помощь с фоновыми функциями. Пример: я печатаю на кнопках 5 + 6. Теперь, когда я нажимаю «=», он должен установить ввод TextBox в переменную, а затем вычислить его. У кого-нибудь есть идея, как я могу это сделать. (Я очень хорошо знал Пауэршелла). Спасибо и извините за мой плохой инглиш. Привет Сандро
