The document provides an example of multiplying two 2x2 matrices. It shows the step-by-step process of multiplying each element of the first matrix with the corresponding column elements of the second matrix. The answer matrix is calculated and presented. It then summarizes the general process for multiplying two 2x2 matrices.

2. [7 -9] [56] [2 -4] [95] Example:

3. First we multiply the first row of the first matrix to the 1st column of the 2nd matrix. [ (7 *5)+ (-9 *9)][ …………. ] [……………………….] [………….. ] And then multiply the first row of the first matrix to the 2nd column of the 2nd matrix [ (7 *5)+ (-9 *9)][ ( 7 * 6 ) + (-9 * 5) ] [……………………….] [………….. ]

4. And then multiply the 2nd row of the first matrix to the 1st column of the 2nd matrix. [ (7 *5)+ (-9 *9)][ ( 7 * 6 ) + (-9 * 5) ] [ (2*5)+ (-4 *9)][ ………………………. ] And then multiply the 2nd row of the first matrix to the 2nd column of the 2nd matrix [ (7 *5)+ (-9 *9)][ ( 7 * 6 ) + (-9 * 5) ] [ (2*5)+ (-4 *9)] [ ( 2 * 6 ) + (-4 * 5) ]

5. ANSWER [ ( 35 + (-81)) ] [ ( 42 + (-45) ) ] [ ( 10 + (-36)) ] [ ( 12 + (-20)) ] _______________________ [ -46 -3 ] [ -26 -8 ] _______________________ Tuh-duh.                                                                                

6. [a b] [E F] = [(A*E)+(B*G) [(A*F)+(B*H)] [C d] [G H] = [(C*E)+(D*G) [(C*F)+(D*H)] Therefore we conclude that a 2x2 matrix has a process like this….
