The increase and multiplication of the world.
--Thackeray.
2. (Math.) The process of repeating, or adding to itself, any
given number or quantity a certain number of times;
commonly, the process of ascertaining by a briefer
computation the result of such repeated additions; also,
the rule by which the operation is performed; -- the
reverse of division.
Note: The word multiplication is sometimes used in
mathematics, particularly in multiple algebra, to
denote any distributive operation expressed by one
symbol upon any quantity or any thing expressed by
another symbol. Corresponding extensions of meaning are
given to the words multiply, multiplier, multiplicand,
and product. Thus, since [phi](x + y) = [phi]x + [phi]y
(see under {Distributive}), where [phi](x + y), [phi]x,
and [phi]y indicate the results of any distributive
operation represented by the symbol [phi] upon x + y,
x, and y, severally, then because of many very useful
analogies [phi](x + y) is called the product of [phi]
and x + y, and the operation indicated by [phi] is
called multiplication. Cf. {Facient}, n., 2.
3. (Bot.) An increase above the normal number of parts,
especially of petals; augmentation.
4. The art of increasing gold or silver by magic, --
attributed formerly to the alchemists. [Obs.] --Chaucer.
{Multiplication table}, a table giving the product of a set

numbers multiplied successively by 1, 2, 3, etc., up to 10
or 12.
Compound substances are made up of two or more simple

{Compound engine} (Mech.), a form of steam engine in which
the steam that has been used in a high-pressure cylinder
is made to do further service in a larger low-pressure
cylinder, sometimes in several larger cylinders,
successively.
{Compound ether}. (Chem.) See under {Ether}.

or more screws with different pitch (a differential
screw), or running in different directions (a right and
left screw).

measures are combined in one; as, 6-8 time is the joining
of two measures of 3-8 time.
