E is a symbol representing a number in mathematics, but it is not limited to the field of mathematics. In nature, structure, shape, interest rate or hyperbolic area, calculus textbooks, Bernoulli family, etc. Now e has been calculated to two thousand decimal places.

E is the base of natural logarithm, and it is an infinite acyclic decimal with the value of 2.7 1828 ... It is defined as follows: when n→∞, the limit of (1+ 1/n) N Note: X Y stands for the Y power of X.

(2)e (scientific symbol)

In the scientific counting method, in order to make the formula simple, it can be expressed in a format with "e". For example, 1.03 multiplied by the eighth power of 10 can be abbreviated as "1.03E+08".

Expressions related to scientific counting methods:

(1) 3×104+4×104 = 7×104, that is, aebec = ﹙ ab ﹚ EC.

(2) 3E6× 6E5 =18e11=1.8e12, that is aEM×bEN=abE(M+N).

(3)-6E4÷3E3=-2E 1, that is, aEM÷bEN=a/bE(M-N).
