java.lang.ClassCastException: android.widget.Button[] невозможно привести к android.widget.Button в «com.calculator_app.MainActivity.onCreate$lambda$0(MainActivity.kt:60)»
it особенно упомянув строку номер #60. я проверил, но не понял проблемы.
вот мой основной код активности, я разрабатываю калькулятор, где я использовал множество кнопок на экране xml

Я разрабатываю цифровой калькулятор.
