Multiplication of two matrices possible if the number of columns in the first matrix equals the number of rows in the second matrix.Multiplication of two matrices possible if the number of columns in the first matrix equals the number of rows in the second matrix.
Let A be the first matrix and B be the second matrix.
\The dimensions of the matrix A are ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=be9e009cd45d3524ff35346d2c50a40f.png\")
and the number of columns in the matrix A is 2.
The dimensions of the matrix B are ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=d2d22c832864cb147315f5524ed7f196.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 A is not equals the number of rows in the matrix B.
\So, matrix product AB is impossible.![\"\"](\"http://www.mathskey.com/userfiles/image/steps_images/solution.JPG\")
The matrix product AB is impossible.
