Quick and simple explanation by premath.com Ok, so how do we multiply two matrices? Check the compatibility of the matrices given.

Both The Size Of The Matrices And The Order We Multiply Them In Matters.


Make sure that the number of columns in the 1 st matrix equals the number of rows in the 2 nd matrix (compatibility of matrices). Recall that the size of a matrix is the number of rows by the number of columns. However, if we reverse the order, they can be multiplied.

When Multiplying Matrices, The Size Of The Two Matrices Involved Determines Whether Or Not The Product Will Be Defined.


Because the expression a+a is the sum of two matrices with the same dimensions, a matrix a can be added to itself. In order for matrix multiplication to work, the number of columns of the left matrix must equal to the number of rows of the right matrix. Two matrices can only be multiplied if the number of columns of the matrix on the left is the same as the number of rows of the matrix on the right.
