The mathematical symbol ln is the abbreviation of natural logarithm, so it can't be read as a word. Some people try to read continuously, but it is not ideal. Usually read as log, ln stands for the natural logarithmic symbol based on the constant e in mathematics. That is, lnm=loge(m), where log (English noun: logarithm) stands for logarithmic operation.

The natural logarithm in the field of mathematics is represented by ln, the first letter is lowercase L, not uppercase I, and Ln is the natural logarithm ln a=loge? A. Logarithms based on e are usually used for ln, and e is also a transcendental number. E is widely used in science and technology, and the logarithm with the base of 10 is generally not used. Taking e as the base can simplify many formulas, and it is the most "natural", so it is called "natural logarithm" When a b = n, it can also be expressed as log (a) (n) = b, where a is called "base", n is called "true number" and b is called "logarithm of n with base a". The log(a)(n) function is called logarithmic function.
