The base of natural logarithm is as big as the speed of a spaceship and as small as the spiral of a snail. Who can leave it? 2。 The most important constant π is included in it.

The most perfect plane symmetrical figure in the world is a circle. Can the "greatest formula" leave pi? 3。 The most important operation symbol+is contained in it.

The plus sign is the most important symbol because all other symbols are derived from the plus sign. The minus sign is the inverse of addition, and multiplication is accumulation. ...

4。 The most important relational symbol = is included in it.

I believe that you have just learned arithmetic, and you will agree with this sentence in this situation.

5。 The most important two dollars are in it.

Zero element 0 and unit element 1 are the basic elements of constructing groups, rings and domains. If you read a book about modern algebra, you will realize its importance.

6。 The most important imaginary unit I is also among them.

The imaginary unit I extends the problem on the number axis to the plane, which cannot be retained in hamill's 4 yuan number and Gloria's 8 yuan number.

5。 I say she is beautiful because of the simplification of this formula. She has no redundant characters, but she is related to almost all mathematical knowledge.

With the plus sign, you can get the rest of the operation symbols;

With 0, 1, you can get other numbers;

With π, there is a circular function, which is a trigonometric function;

With I, there is an imaginary number, and the plane vector corresponds to it, so there is hamill's 4 yuan number, and the real space corresponds to it;

With e, there is calculus, and there is mathematics suitable for the industrial revolution.
