Definition:Prosthaphaeresis/Logarithms

Definition
The logarithmic technique of prosthapheiresis is based on the rule of the Sum of Logarithms:
 * $\log_b x y = \log_b x + \log_b y$

Any base $b$ can be used.

The original tecnhique used Napierian logarithms where the base was $0.9999999$

In due course the common (base $10$) logarithm was used, as developed by, called Briggsian logarithms.
