Ln calculation step by step

To calculate the natural logarithm (ln) of a number, follow these steps:

  1. Enter the number whose natural logarithm you want to find in your calculator.
  2. Press the “ln” button. This will give you the natural logarithm of the number you entered.

For example, to find the natural logarithm of 10:

  1. Enter 10 in your calculator.
  2. Press the “ln” button.
  3. The result will be approximately 2.3026.

Therefore, ln(10) = 2.3026.


The natural logarithm, denoted as ln, is the logarithm to the base of e, where e is an irrational constant approximately equal to 2.71828. The ln function gives the power to which e must be raised to obtain a given number.

For example, the natural logarithm of x (ln(x)) can be calculated as:

ln(x) = log_e(x) = y

Where e is the mathematical constant approximately equal to 2.71828, x is the value to take the natural logarithm of, and y is the result of the natural logarithm.

The ln function can be calculated using a scientific calculator or using software such as Microsoft Excel.
