Multiplication \Mul`ti*pli*ca"tion\, n. [L. multiplicatio: cf.
F. multiplication. See {Multiply}.]
1. The act or process of multiplying, or of increasing in
number; the state of being multiplied; as, the
multiplication of the human species by natural generation.
[1913 Webster]

--Thackeray.

2. (Math.) The process of repeating, or adding to itself, any

commonly, the process of ascertaining by a briefer

the rule by which the operation is performed; -- the
reverse of division.
[1913 Webster]
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.
[1913 Webster]
3. (Bot.) An increase above the normal number of parts,
especially of petals; augmentation.
[1913 Webster]
4. The art of increasing gold or silver by magic, --
attributed formerly to the alchemists. [Obs.] --Chaucer.

elementary school prior to memorization of the table.
[1913 Webster]
