3x2

3x2 is a compact notation used in mathematics and related fields that can refer to several related concepts. Most commonly, it denotes a multiplication expression: 3 times 2, which equals 6. The symbol x is used as the multiplication operator; commutativity means that 3x2 equals 2x3, both yielding 6. In programming and mathematics, other symbols such as the dot (·) or the asterisk (*) may be used for multiplication, but x is a familiar form in plain-text notation.

In linear algebra, 3x2 describes a matrix with 3 rows and 2 columns, written as a 3-by-2

Geometrically, a 3x2 rectangle or grid has three units in one dimension and two in the other,
