Basic Operations Possible only if matrices have the same dimensions ( ). You add corresponding elements: Scalar Multiplication ( You add corresponding elements: Scalar Multiplication ( ):

): A scalar value that can be computed from the elements of a square matrix. It characterizes many properties of the matrix, such as whether it is invertible. A matrix such that It is used to solve systems of linear equations

is the identity matrix. It is used to solve systems of linear equations. Formed by swapping rows and columns: Educational Resources for Solutions
