I think Lin is very lonely in mathematics! For example, when our junior middle school is odd or even, the math teacher always likes to carry zero out by himself. Later, we began to learn positive and negative numbers and kicked out zero.

Later, I learned a lot of mathematical formulas, and many times zero is the most special one. When learning square, the teacher always reminds us that the zeroth power of any number is equal to one. When we were studying, the teacher asked us to remember that a class with zero equals one.

I feel that the number zero is really lonely and I can't get along with anyone.
