Matrices Class 12 NCERT Solutions introduces the concept of matrices and the basic laws of matrix algebra, which is an important instrument in the field of mathematics. When compared to other direct techniques, this mathematical tool greatly simplifies complicated calculations. The notion of matrices stems from a desire to find quick and easy techniques to solve a system of linear equations. This mathematical tool is now utilised in genetics, economics, sociology, contemporary psychology, and industrial management, among other specific fields of research. When it comes to academics, this topic is crucial for both the CBSE board test and competitive examinations.

Example:

This matrix is of the order 3 x 3 as it has 3 rows (i) and 3 columns (j).

Similarly,

[ 1 2 3]

This matrix is of the order 1 x 3 as it has one row (i) and 3 columns (j).
