Не уверен, что понять, что logcat говорит мне, неправильно

Это ошибка, которую дает мой логарифм. Я понимаю, что это имеет какое-то отношение к моему editText, но я не уверен, что. Я надеюсь, что его глупая ошибка, которая может быть исправлена быстро и легко, поэтому я могу продолжать работать как можно скорее. Помогите мне, если вы можете Stackoverflow Спасибо!

Ошибка возникает только при запуске программы
