Addition and Subtraction of Matrices.
Please Note that only matrices which are of the same order (the same number of rows and columns) can be added or subtracted. You might go through the exercises and practice noting of which order they are in - remember that the number of rows are mentioned first and then the number of columns.
To ADD, each element of the first matrix is added to the corresponding element of the other.
To SUBTRACT, each element of the second matrix is subtracted from the corresponding element of the first matrix.
Please do : Ex 12(A) : 6, 4. 5, 10 and 11 (Please do the sums in the order I have given - you will probably find it easier than going in chronological order).
Please contact me if you have any difficulty.
Enjoy Maths !
