On the word 150 math diary?
Yesterday, my grandma and I went to the drugstore and bought two boxes of pills-two boxes of stomach Shu Ning, one box of 52 yuan and one box of 26 yuan. Grandma gave her 100 yuan, and the shop assistant gave it to grandma 48 yuan. After I found the change, I calculated it with decimal addition and subtraction. Grandma can also pay like this: 1. Give it to 50 yuan, the shop assistant, and then give it to 10 yuan for 8 yuan. If grandma has change, she can pay 50 yuan first and then 2 yuan. By buying medicine with grandma this time, I know that mathematics is closely related to our lives.

Yesterday, I got 95 points in the math tutoring exam. I made a mistake in filling in the blanks and writing questions. The teacher reviewed the fill-in-the-blank questions for us before the exam. I didn't recite it carefully, but I remembered it carefully. I was thinking about something else when I recited it, and I didn't remember it at all. So when I took the exam, I couldn't remember it anyway, so I just filled in the numbers. I didn't see the meaning of the title clearly, so it was wrong to write "X" as "+". This grade, the first 1 question is because my attitude is not correct, and the second question is because I didn't review it carefully. I will definitely do these two things in the future, but I can't be careless. Teacher, I can't get satisfactory results in every exam. Since I took interesting math, I understand that the most important thing in learning math is understanding. It's no use just copying other people's answers. It's no use copying them. So I will listen carefully in the future and strive for excellent results.
