> An operation shows itself in a variable; it shows how we can proceed from one form of proposition to another.

An operation is revealed through a variable, indicating the method of moving from one propositional form to another.

_Clarifies the role of operations in logical transformations._

> It gives expression to the difference between the forms. (And that which is common to the bases, and the result of an operation, is the bases themselves.)

The operation articulates the distinction between forms, and the bases themselves are what the bases and the operation's result share.
