mul·ti·pli·ca·tion (m?l?t?-pl?-k??sh?n)n.1. The act or process of multiplying or the condition of being multiplied.2. Propagation of plants and animals; procreation.3. Mathematics a. The operation that, for positive integers, consists of adding a number (the multiplicand) to itself a certain number of times. The operation is extended to other numbers according to the multiplicative properties of positive integers and other algebraic properties.b. Any of certain analogous operations involving mathematical objects other than numbers.mul?ti·pli·ca?tion·al adj.American Heritage® Dictionary of the English Language, Fifth Edition.

(Mathematics) an arithmetical operation, defined initially in terms of repeated addition, usually written a × b, a.b, or ab, by which the product of two quantities is calculated: to multiply a by positive integral b is to add a to itself b times. Multiplication by fractions can then be defined in the light of the associative and commutative properties; multiplication by 1/n is equivalent to multiplication by 1 followed by division by n: for example 0.3 × 0.7 = 0.3 × = (0.3 × 7)/10 = 2 = 0.212. the act of multiplying or state of being multiplied3.
