For example you can add two or more 3 3 1 2 or 5 4 matrices. A multiplying a 2 3 matrix by a 3 4 matrix is possible and it gives a 2 4 matrix as the answer. You cannot add a 2 3 and a 3 2 matrix a 4 4 and a 3 3 etc. So first we list the entries column by column to get the matrix as follows.

We can only multiply matrices if the number of columns in the first matrix is the same as the number of rows in the second matrix. Provided that they have the same size each matrix has the same number of rows and the same. A matrix c 1 3 2 4 nrow 2 the nrow 2 command tells r that the matrix has 2 rows then r can compute the number of columns by dividing the length of the vector by nrow. For example the dimension of the matrix below is 2 3 read two by three because there are two rows and three columns.
