  2. L.O. Multiply matrices by scalars and other matrices Paula and Greg want to compare the cost of shopping at two supermarkets.

  3. L.O. Multiply matrices by scalars and other matrices Paula and Greg want to compare the cost of shopping at two supermarkets. (2 x 3) x (3 x 2)  (2 x 2) The number of columns in the first must equal the number of rows in the second

  4. L.O. Multiply matrices by scalars and other matrices The element in the product tells us the row of the first and the column of the second (2 x 120)

  5. L.O. Multiply matrices by scalars and other matrices The element in the product tells us the row of the first and the column of the second (2 x 120) + (4 x 55)

  6. L.O. Multiply matrices by scalars and other matrices The element in the product tells us the row of the first and the column of the second (2 x 120) + (4 x 55) + (5 x 35) = 635

  7. L.O. Multiply matrices by scalars and other matrices The element in the product tells us the row of the first and the column of the second (2 x 120) + (4 x 55) + (5 x 35) = 635

  8. L.O. Multiply matrices by scalars and other matrices The element in the product tells us the row of the first and the column of the second (2 x 120) + (4 x 55) + (5 x 35) = 635 (2 x 110)

  9. L.O. Multiply matrices by scalars and other matrices The element in the product tells us the row of the first and the column of the second (2 x 120) + (4 x 55) + (5 x 35) = 635 (2 x 110) + (4 x 60)

  10. L.O. Multiply matrices by scalars and other matrices The element in the product tells us the row of the first and the column of the second (2 x 120) + (4 x 55) + (5 x 35) = 635 (2 x 110) + (4 x 60) + (5 x 30) = 610

  11. L.O. Multiply matrices by scalars and other matrices The element in the product tells us the row of the first and the column of the second (2 x 120) + (4 x 55) + (5 x 35) = 635 (2 x 110) + (4 x 60) + (5 x 30) = 610 (1 x 120) +

  12. L.O. Multiply matrices by scalars and other matrices The element in the product tells us the row of the first and the column of the second (2 x 120) + (4 x 55) + (5 x 35) = 635 (2 x 110) + (4 x 60) + (5 x 30) = 610 (1 x 120) + (7 x 55) +

  13. L.O. Multiply matrices by scalars and other matrices The element in the product tells us the row of the first and the column of the second (2 x 120) + (4 x 55) + (5 x 35) = 635 (2 x 110) + (4 x 60) + (5 x 30) = 610 (1 x 120) + (7 x 55) + (3 x 35) = 610
