The act or process of multiplying or the condition of being multiplied.

Propagation of plants and animals; procreation.

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.

Any of certain analogous operations involving mathematical objects other than numbers.

A dice-game in which the highest of three dice thrown is left on the table. The remaining two are thrown again, and the higher left, and then the third is thrown as a multiplier of the sum of the other two. The player who gets the highest total in this way wins.

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.

An arithmetical process in which one number, the multiplier, is considered as an operator upon another, the multiplicand, the result, called the product, being the total number of units in as many groups as there are units in the multiplier, each group being equal in number to the multiplicand; more generally, the operation of finding the quantity which results from substituting the multiplicand in place of unity in the multiplier.

(a + b) (c + d) = ac + bc + ad + bd.

Under certain restrictions, all multiplication follows the associative principle, expressed by the formula a (bc) = (ab)c. According to the nature of the conjunction of units, multiplication does or does not follow the commutative principle, expressed by the formula ab = ba.
