British Dictionary definitions for multiplication

multiplication

/ˌmʌltɪplɪˈkeɪʃən/
noun
1.
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 × 7/10 = (0.3 × 7)/10 = 21/10 = 0.21
2.
the act of multiplying or state of being multiplied
3.
the act or process in animals, plants, or people of reproducing or breeding

multiplication
  (mŭl'tə-plĭ-kā'shən)   
  1. A mathematical operation performed on a pair of numbers in order to derive a third number called a product. For positive integers, multiplication consists of adding a number (the multiplicand) to itself a specified number of times. Thus multiplying 6 by 3 means adding 6 to itself three times. The operation of multiplication is extended to other real numbers according to the rules governing the multiplicational properties of positive integers.

  2. Any of certain analogous operations involving expressions other than real numbers.
