Multiplication of two matrices possible if the number of columns in the first matrix equals the number of rows in the second matrix.
\The dimensions of the matrix S are ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=612e879b17f6683deffbb9d2e26f1a4e.png\")
and the number of columns in the matrix S is 2.
The dimensions of the matrix T are ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=a3b63ce2a0f38f3bc3f093c5cc42c5cf.png\")
and the number of the rows in the matrix T is 2.![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/step2.JPG\")
The number of columns in the matrix S equals the number of rows in the matrix T.
\So, matrix product ST is possible.
\Its dimensions are ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=ec7c6ec3cc576f9d953da5f25b534953.png\")
