Hello! First of all, I would like to say to you that I am sorry for letting you down. I failed miserably in the final math exam, which not only broke your heart, but also made me ashamed. I analyzed the reasons for this failure. Most of them were caused by my carelessness, but I didn't understand a few of them. You often warn us, but I can't change my carelessness. However, I should not give myself reasons, rest assured, teacher, I will correct.
