You can put this solution on YOUR website! A is a 2 rows by 3 columns matrix
B is a 2 rows by 3 columns matrix
:
therefore (A+B) is a 2 rows by three columns matrix
:
C is a 3 rows by 2 columns matrix
:
therefore, C(A+B) is defined and it is a 2 by 2 matrix
:
(A+B) is
1 5 -3
-5 10 7
:
Note that we add corresponding elements of both matrices
:
C(A+B) is
:
6+30+9 1+20-12
-30+60-21 -5+40+28
:
45 9
9 63
:
Note that we multiply the elements of each row by the elements of each column
