Day 90/100: The Multiplication Symbol (×). Arithmetic: the symbol (⋅), (×), or (∗) between two mathematical expressions denotes multiplication of the second expression by the first. In mathematics, the symbol × has a number of uses, including: • Multiplication of two scalar numbers, where it is read as "times" or "multiplied by" • Cross product of two vectors, where it is usually read as "cross" • Cartesian product of two sets, where it is usually read as "cross" • Geometric dimension of an object, such as noting that a room is 10 feet × 12 feet in area • Dimensions of a matrix, where it is usually read as "by" In biology, the multiplication sign is used in a botanical hybrid name (botany), for instance Ceanothus papillosus × impressus (a hybrid between C. papillosus and C. impressus).
