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 P are ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=ac5d6352dcd1112f6c2ecf2f4d791531.png\")
and the number of columns in the matrix A is 3.
The dimensions of the matrix Q are ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=510efb2e33044679a02534b6053b5e5b.png\")
and the number of the rows in the matrix B is 3.![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/step2.JPG\")
The number of columns in the matrix P equals the number of rows in the matrix Q.
\So, matrix product PQ is possible.
\Its dimensions are ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=3301cd1125e78fde542f19d687e3ee8c.png\")
