создать калькулятор с GUI оболочки PowerShell

так Привет, ребята
Я пытаюсь создать калькулятор. До сих пор у меня в GUI закончил. Но мне нужна помощь с backgroundfunctions. Пример: набираю на кнопках 5+6. Теперь, когда я нажимаю"=", он должен установить ввод текстового поля в переменную, а затем вычислить его. У кого-то есть идея, как я могу это сделать. (Im довольно знал Powershell).
Спасибо и простите за мой плохой английский.
Приветствия
Sandro

следующее улучшение моего предыдущего ответа на ваш почти тот же вопрос смогло помочь однако такая заплатка проводила бы вас к погибели (также, как я). Удачи вам!
