  2. Matrix Multiplication Row by Column Jeff Bivin -- LZHS

  3. Let’s Begin………. Jeff Bivin -- LZHS

  4. Row 1 X Column 1 3 x 5+ 5 x 3 = 30 Jeff Bivin -- LZHS

  5. Row 1 X Column 1 3 x 5 + 5x3 =30 Jeff Bivin -- LZHS

  6. Row 1 X Column 1 = A(1,1) Jeff Bivin -- LZHS

  7. Row 1 X Column 2 3 x 2+ 5 x 4 = 26 Jeff Bivin -- LZHS

  8. Row 1 X Column 2 3 x 2 + 5 x 4 =26 Jeff Bivin -- LZHS

  9. Row 1 X Column 2 = A(1,2) Jeff Bivin -- LZHS

  10. Row 2 X Column 1 -2 x 5+ 1 x 3 = -7 Jeff Bivin -- LZHS

  11. Row 2 X Column 1 -2 x 5 + 1 x 3 = -7 Jeff Bivin -- LZHS

  12. Row 2 X Column 1 = A(2,1) Jeff Bivin -- LZHS

  13. Row 2 X Column 2 -2 x 2+ 1 x 4 = 0 Jeff Bivin -- LZHS

  14. Row 2 X Column 2 -2 x 2 + 1 x 4 = 0 Jeff Bivin -- LZHS

  15. Row 2 X Column 2 = A(2,2) Jeff Bivin -- LZHS

  16. Row 3 X Column 1 4 x 5+ 9 x 3 = 47 Jeff Bivin -- LZHS

  17. Row 3 X Column 1 4 x 5 + 9 x 3 = 47 Jeff Bivin -- LZHS

  18. Row 3 X Column 1 = A(3,1) Jeff Bivin -- LZHS

  19. Row 3 X Column 2 4 x 2+ 9 x 4 = 44 Jeff Bivin -- LZHS

  20. Row 3 X Column 2 4 x 2 + 9 x 4 = 44 Jeff Bivin -- LZHS

  21. Row 3 X Column 2 = A(3,2) Jeff Bivin -- LZHS

  22. A Quick Review Jeff Bivin -- LZHS

  23. Row 1 X Column 1 = A(1,1) Jeff Bivin -- LZHS

  24. Row 1 X Column 2 = A(1,2) Jeff Bivin -- LZHS

  25. Row 2 X Column 1 = A(2,1) Jeff Bivin -- LZHS

  26. Row 2 X Column 2 = A(2,2) Jeff Bivin -- LZHS

  27. Row 3 X Column 1 = A(3,1) Jeff Bivin -- LZHS

  28. Row 3 X Column 2 = A(3,2) Jeff Bivin -- LZHS

  29. Matrix Multiplication = Jeff Bivin -- LZHS
