    1. 1. Multiplication Wrestling
    2. 2. What is 78 X 36?
    3. 3. What is 78 X 36? How do we solve this?
    4. 4. What is 78 X 36? How do we solve this? Think....FOIL
    5. 5. What is FOIL?
    6. 6. What is FOIL? F- First Two
    7. 7. What is FOIL? F- First Two O- Outter Two
    8. 8. What is FOIL? F- First Two O- Outter Two I- Inner Two
    9. 9. What is FOIL? F- First Two O- Outter Two I- Inner Two L- Last Two
    10. 10. Step 1: Turn your multiplication fact into a partial sum fact.
    11. 11. 78 X 36= (70 + 8) X (30 +6)
    12. 12. Step 2: Find the FOIL
    13. 13. Step 2: Find the FOIL (70 + 8) x (30 + 6) F-First Two (70 x 30)
    14. 14. Step 2: Find the FOIL
    15. 15. Step 2: Find the FOIL (70 +8) x (30 + 6)
    16. 16. Step 2: Find the FOIL (70 +8) x (30 + 6) O- Outter Two
    17. 17. Step 2: Find the FOIL (70 +8) x (30 + 6) O- Outter Two (70 x 6)
    18. 18. Step 2: Find the FOIL
    19. 19. Step 2: Find the FOIL (70 + 8) x (30 +6)
    20. 20. Step 2: Find the FOIL (70 + 8) x (30 +6) I- Inner Two
    21. 21. Step 2: Find the FOIL (70 + 8) x (30 +6) I- Inner Two (8 x 30)
    22. 22. Step 2: Find the FOIL
    23. 23. Step 2: Find the FOIL (70 + 8) x (30 + 6)
    24. 24. Step 2: Find the FOIL (70 + 8) x (30 + 6) L- Last Two
    25. 25. Step 2: Find the FOIL (70 + 8) x (30 + 6) L- Last Two (8 x 6)
    26. 26. Step 3: Add up the FOIL
    27. 27. Step 3: Add up the FOIL F- (70 x 30) = 2100
    28. 28. Step 3: Add up the FOIL F- (70 x 30) = 2100 O- (70 x 6)= 420
    29. 29. Step 3: Add up the FOIL F- (70 x 30) = 2100 O- (70 x 6)= 420 I- (8 x 30)= 240
    30. 30. Step 3: Add up the FOIL F- (70 x 30) = 2100 O- (70 x 6)= 420 I- (8 x 30)= 240 L- (8 x 6)= 48
    31. 31. Step 3: Add up the FOIL F- (70 x 30) = 2100 O- (70 x 6)= 420 I- (8 x 30)= 240 L- (8 x 6)= 48 2100+ 420 + 240 + 48= 2,808
    32. 32. SO... 78 x 36 = 2,808
    33. 33. 27 x 45
    34. 34. 27 x 45 (20 + 7) x (40 + 5)
    35. 35. 27 x 45 (20 + 7) x (40 + 5) F- (20 x 40)
    36. 36. 27 x 45 (20 + 7) x (40 + 5) F- (20 x 40) O- (20 x 5)
    37. 37. 27 x 45 (20 + 7) x (40 + 5) F- (20 x 40) O- (20 x 5) I- (7 x 40)
    38. 38. 27 x 45 (20 + 7) x (40 + 5) F- (20 x 40) O- (20 x 5) I- (7 x 40) L- (7 x 5)
    39. 39. 27 x 45 (20 + 7) x (40 + 5) F- (20 x 40) O- (20 x 5) I- (7 x 40) L- (7 x 5) 800 + 100+280+35= 1215
    40. 40. 93 x 76
    41. 41. 93 x 76 (90 + 3) x (70 + 6)
    42. 42. 93 x 76 (90 + 3) x (70 + 6) F- (90 x 70)
    43. 43. 93 x 76 (90 + 3) x (70 + 6) F- (90 x 70) O- (90 x 6)
    44. 44. 93 x 76 (90 + 3) x (70 + 6) F- (90 x 70) O- (90 x 6) I- (3 x 70)
    45. 45. 93 x 76 (90 + 3) x (70 + 6) F- (90 x 70) O- (90 x 6) I- (3 x 70) L- (3 x 6)
    46. 46. 93 x 76 (90 + 3) x (70 + 6) F- (90 x 70) O- (90 x 6) I- (3 x 70) L- (3 x 6) 6300+540+210+18= 7068
