Speculative painting, without the assistance of
manual operation, can never attain to perfection.
--Dryden.
[1913 Webster]
2. The method of working; mode of action.

about in accordance with a definite plan; as, military or
naval operations.
[1913 Webster]
4. Effect produced; influence. [Obs.]
[1913 Webster]
The bards . . . had great operation on the vulgar.
--Fuller.
[1913 Webster]
5. (Math.) Something to be done; some transformation to be
made upon quantities or mathematical objects, the
transformation being indicated either by rules or symbols.
[1913 Webster]
6. (Surg.) Any methodical action of the hand, or of the hand
with instruments, on the human body, to produce a curative
or remedial effect, as in amputation, etc.
[1913 Webster]
Calculus of operations. See under Calculus.

Calculus \Cal"cu*lus\, n.; pl. Calculi. [L, calculus. See
Calculate, and Calcule.]
1. (Med.) Any solid concretion, formed in any part of the
body, but most frequent in the organs that act as
reservoirs, and in the passages connected with them; as,
biliary calculi; urinary calculi, etc.
[1913 Webster]
2. (Math.) A method of computation; any process of reasoning
by the use of symbols; any branch of mathematics that may
involve calculation.
[1913 Webster]
Barycentric calculus, a method of treating geometry by
defining a point as the center of gravity of certain other
points to which co["e]fficients or weights are ascribed.
Calculus of functions, that branch of mathematics which
treats of the forms of functions that shall satisfy given
conditions.
Calculus of operations, that branch of mathematical logic
that treats of all operations that satisfy given
conditions.
Calculus of probabilities, the science that treats of the
computation of the probabilities of events, or the
application of numbers to chance.
Calculus of variations, a branch of mathematics in which
the laws of dependence which bind the variable quantities
together are themselves subject to change.
Differential calculus, a method of investigating
mathematical questions by using the ratio of certain
indefinitely small quantities called differentials. The
problems are primarily of this form: to find how the
change in some variable quantity alters at each instant
the value of a quantity dependent upon it.
Exponential calculus, that part of algebra which treats of
exponents.
Imaginary calculus, a method of investigating the relations
of real or imaginary quantities by the use of the
imaginary symbols and quantities of algebra.
Integral calculus, a method which in the reverse of the
differential, the primary object of which is to learn from
the known ratio of the indefinitely small changes of two
or more magnitudes, the relation of the magnitudes
themselves, or, in other words, from having the
differential of an algebraic expression to find the
expression itself.
