Answer:
( 2, -2 )T + ( 8, 6 )T = ( 10, 4 )T
( 2, -2 )T + ( 8, 6 )T = ( 10, 4 )T
The matrices you add must be of the same dimension and same row or column type. When you add matrices, each dimension is handled independently of the others. For example, in adding two 3D column matrices, you have three separate additions using ordinary arithmetic. The first elements of the operand matrices are added together to make the first element of the result matrix.
Do the following problems:
( 8, 4, 6 )T + ( 2, -2, 9 )T = ( )T ( 2, -2, 9 )T + ( 8, 4, 6 )T = ( )T
