This worksheet will help you to know about concept of Matrix Addition. Let A & B are the two 3x3 matrices. A 3x3 matrix is a square array of numbers having 3 columns and 3 rows. The resulting matrix addition will have the same number of rows as matrix A and the same number of columns as B. The 3 x 3 Matrix addition formula is given below,

For Example:

Matrix A =
 1 2 3 4 5 6 7 8 9

Matrix B =
 1 2 3 4 5 6 7 8 9

Matrix A+B =
 1+1 2+2 3+3 4+4 5+5 6+6 7+7 8+8 9+9

Matrix A+B =
 2 4 6 8 10 12 14 16 18
