一直以来,对0有一种特别的情感,这种情感到了初中时更为强烈。自从认识0以来,一直认为它是一无是处的,它与其他数相加,结果与0无关,还是其他的数。但到了初中以后,老师告诉我们,求一个数的相反数就是在这个数前面加一个负号,但在这么多个数当中,只有0加完负号后,依然还是0。刚刚听到这个结论时,我不由得嘲笑道“固执的0”。但仔细思索却猛然醒悟,0依然是0,它只做它自己。无论其他数如何加减如何变化,它依然只做自己,其他数都变了,只有它保留着自己的本性,永远不因为他人 For a long time, there was a special emotion to 0, which was stronger in junior high school. Since the recognition of 0, it has been considered to be useless. It has been added to other numbers and the result has nothing to do with 0 or other numbers. However, after junior high school, the teacher told us that the inverse of a number is to add a negative sign in front of the number, but among such numbers, only 0 plus the negative sign remains 0. When I just heard this conclusion, I couldn’t help laughing at the “sticky 0”. But when you think about it and wake up suddenly, 0 is still 0. It only does it itself. No matter how the other number changes, it still only does it himself. Other numbers have changed. Only it retains its own nature, never because of others.
