Dictionary Meaning and Definition on 'Multiplication'
- an arithmetic operation that is the inverse of division; the product of two numbers is computed; "the multiplication of four by three gives twelve"; "four times three equals twelve" [syn: times]
- the act of producing offspring or multiplying by such production [syn: generation, propagation]
- a multiplicative increase; "repeated copying leads to a multiplication of errors"; "this multiplication of cells is a natural correlate of growth"
- Multiplication \Mul`ti*pli*ca"tion\, n. [L. multiplicatio: cf.
F. multiplication. See Multiply.]
- 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. The increase and multiplication of the world. --Thackeray.
- (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.
- (Bot.) An increase above the normal number of parts, especially of petals; augmentation.
- The art of increasing gold or silver by magic, -- attributed formerly to the alchemists. [Obs.] --Chaucer.

Wikipedia Meaning and Definition on 'Multiplication'
Multiplication is an arithmetic operation for finding the product of two numbers. Multiplication is the third operation in maths after addition which is the first, subtraction which is the second and then there is multiplication.
With natural numbers, it tells you the number of tiles in a rectangle where one of the two numbers equals the number of tiles on one side and the other number equals the number of tiles on the neighbouring side.
With real numbers, it tells you the area of a rectangle where the first number equals the size of one side and the second number equals the size of the neighbouring side.
For example, three multiplied by five is the total of five threes added together, or the total of three fives. This can be written down as 3 × 5 = 15, or spoken as "three times five equals fifteen." Mathematicians call the two numbers you wish to multiply "coefficients" together, or "multiplicand" and "multiplicator" separately. Multiplicand × multiplicator = product.[See more about Multiplication at Dictionary 3.0 Encyclopedia]
