For adding matrices, their dimension should be equal.
\First write the dimension of the matrix.
\The first matrix is, ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=0f9ceb8712149b9899b874cd7f0fdc61.png\")
The matrix has 2 row and 2 columns, so dimensions of matrix are ![\"\"](\"http://www.mathskey.com/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=005d206c92b8d7c609a15bd3eef2db91.png\")
.
