Mathematics Weekly 100, the first volume of grade four, is a mysterious number, as elusive as a mystery in the universe. 0 is also an important number. If you accidentally add an extra 0 or a less 0, the consequences are really unimaginable.
This math exam really made me realize the importance of 0. It was 99 points when the test paper was handed out! I made a mistake at once. The result made me dumbfounded. The result is 45000-90. "How could I make a mistake with such a simple question?" I muttered to myself. I remember that when I dictated the 45,000-90 question, I easily wrote down 50, and I was still very confident. But in the end, I got 500, which was a 0. How wrong it is! What should not be wrong is also wrong. How important 0 must be!
If I become the financial general manager of the company in the future and someone else comes to withdraw money, I would have taken 10000 yuan, but I added 0- 100000 yuan more, and I still put 10000 yuan on the bill. Then who should I ask for this 90 thousand yuan? I will bear all the consequences!
Through this incident, I understand that I should be meticulous in my work and study, otherwise the consequences will be very serious.

We went downstairs by elevator, and my sister suddenly asked me, "Sister, do you know what math knowledge is used in the elevator?" After I hesitated for two seconds, I excitedly replied to her, "Oh, I see, I used the knowledge of object translation we just learned." My sister pinched my little nose and said, "Smart, I'm a little disappointed that I didn't beat you!" " "... we didn't go home until we had lunch. It's really hot at home! I quickly turned on the fan at home and decided to test my sister: "Do you know what math knowledge it uses?

" "Sister shouted great! Mother sighed and said, "Look, how rich the knowledge of mathematics is and how widely it can be used. You should study math seriously! " "My sister and I nodded attentively.
