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.

The absolute value of ad − bc is the area of the parallelogram, and thus represents the scale factor by which areas are transformed by A. (The parallelogram formed by the columns of A is in general a different parallelogram, but since the determinant is symmetric with respect to rows and columns, the area will be the same.) Learn about the conditions for matrix multiplication to be defined, and about the dimensions of the product of two matrices. Apr 13, 2018 · AB is matrix multiplication. A×B is cross product, which returns a vector. A*B used in computer notation, but not on paper. A•B dot product, which returns a scalar. [See the Vector chapter for more information on vector and scalar quantities.] Note 2 - Commutativity of Matrix Multiplication . Does `AB = BA`? Let's see if it is true using an Matrix Calculator .

a + b + c = 1 Thus, a + b = 1 - c b + c = 1 - a c + a = 1 - b (1/a) + (1/b) + (1/c) = 3 Multiplying both sides by (abc), we get, 1bc/abc + 1ca/bca + 1ab/cab = 3 (ab
