    The most common large format is 4×5 inches (10.2x12.7 cm), which was the size used by cameras like the Graflex Speed Graphic and Crown Graphic, among others. Less common formats include quarter-plate (3.25x4.25 inches (8.3x10.8 cm)), 5×7 inches (12.7x17.8 cm), and 8×10 inches (20×25 cm); the size of many old 1920s Kodak cameras (various versions of Kodak 1, 2, and 3 and Master View cameras ...

    The lower-case Latin letter x is sometimes used in place of the multiplication sign. This is considered incorrect in mathematical writing. This is considered incorrect in mathematical writing. In algebraic notation, widely used in mathematics, a multiplication symbol is usually omitted wherever it would not cause confusion: " a multiplied by b ...

    In third-generation Dodge Ram 2500 trucks, the 10.5 AAM axle was used in all V8-equipped trucks, with some early-model diesel and V10 trucks also adopting this axle. Similar to the 11.5 variant, this axle also features a reusable rubber gasket and bears a resemblance to the 11.5 axle in its appearance.

  8. Row equivalence - Wikipedia

    en.wikipedia.org/wiki/Row_equivalence

    The fact that two matrices are row equivalent if and only if they have the same row space is an important theorem in linear algebra. The proof is based on the following observations: Elementary row operations do not affect the row space of a matrix. In particular, any two row equivalent matrices have the same row space.

    For example, if A is a 3-by-0 matrix and B is a 0-by-3 matrix, then AB is the 3-by-3 zero matrix corresponding to the null map from a 3-dimensional space V to itself, while BA is a 0-by-0 matrix. There is no common notation for empty matrices, but most computer algebra systems allow creating and computing with them.
