Turning multiplication or division into addition or subtraction.

In the days before electronic calculators people used tables of logarithms to the base 10 and tables of their inverses called "anti-logarithms" to compute complicated multiplication or division using only addition or subtraction.

Using the properties of logarithms:

The same is true of division using subtraction.
