Definition of “multiplication”

noun

1. an arithmetical operation, defined initially in terms of repeated addition, usually written an arithmetical operation, defined initially in terms of repeated addition, usually written a  × an arithmetical operation, defined initially in terms of repeated addition, usually written  × b, a.b,  or an arithmetical operation, defined initially in terms of repeated addition, usually written  ×  or ab,  by which the product of two quantities is calculated: to multiply an arithmetical operation, defined initially in terms of repeated addition, usually written  ×  or by which the product of two quantities is calculated: to multiply a  by positive integral an arithmetical operation, defined initially in terms of repeated addition, usually written  ×  or by which the product of two quantities is calculated: to multiply by positive integral b  is to add an arithmetical operation, defined initially in terms of repeated addition, usually written  ×  or by which the product of two quantities is calculated: to multiply by positive integral is to add a  to itself an arithmetical operation, defined initially in terms of repeated addition, usually written  ×  or by which the product of two quantities is calculated: to multiply by positive integral is to add to itself b  times. Multiplication by fractions can then be defined in the light of the associative and commutative properties; multiplication by 1/an arithmetical operation, defined initially in terms of repeated addition, usually written  ×  or by which the product of two quantities is calculated: to multiply by positive integral is to add to itself 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 an arithmetical operation, defined initially in terms of repeated addition, usually written  ×  or by which the product of two quantities is calculated: to multiply by positive integral is to add to itself times. Multiplication by fractions can then be defined in the light of the associative and commutative properties; multiplication by 1/ is equivalent to multiplication by 1 followed by division by n: for example 0.3 × 0.7 = 0.3 × = (0.3 × 7)/10 = 2 = 0.21
2. the act of multiplying or state of being multiplied
3. the act or process in animals, plants, or people of reproducing or breeding
