British Dictionary definitions for 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
