  1. Is the math we teach obsolete? The revolutions in the mathematics of business have had profound and fundamental effects on math education. The What if Math Slideshow

  2. In the year 1202 King Richard the Lionhearted died 1199

  3. Arevolutionary book was published

  4. It defined the mathematics every student is expected to master today 2012 is not 1202

  5. Liber abbaci by Leonardo of Pisa 1202 This virtually unknown work The Book of Calculation

  6. By Leonardo of Pisa

  7. Has had a greater impact than the famous Leonardo’s works

  8. Born in Pisa

  9. Growing up in the 1170’s along with the Leaning Tower

  10. When Pisa was a great trading city

  11. Leonardo joined his trader, diplomat father in Algeria

  12. Where he was tutored in Arabic arithmetic and algebra The Compendious Book on Calculation by Completion and Balancing by al Khwarizmi

  13. Leonardo became a trader too

  14. And used Roman math like all European and Arab merchants did Its technology was the abacus

  15. Roman multiplication by repetition while slow, cumbersome, and error prone 167 x 9 =

  16. None of the cities should be allowed to have its own separate coinage or a system of weights and measures; they should all be required to use ours. Dio Cassius Worked for the Empire

  17. But not for medieval trade where city-states had

  18. Different weights, measures, and currency

  19. Leonardo’s business math using the new paper technology Paper making

  20. Was a huge improvement Algorist vs. abacist

  21. It spread slowly through special schools

  22. Becoming standardized and more symbolic A 16th century merchant’s statement of cash flows

  23. Codified by tutors and their textbooks

  24. Becoming the standard content for business and for schooling The Chapters in Liber abbaci

  25. And Leonardo’s math remains so today

  26. In the year 1979 The Blues Brothers

  27. A revolution changed the mathematics of business

  28. Dan Bricklin, a frustrated Bob Frankston & Dan Bricklin

  29. Harvard Business School student

  30. Working a case study

  31. Found calculators slow, cumbersome, and prone to error

  32. So he invented the spreadsheet VisiCalc the visible calculator

  33. Mitch Kapor added graphs VisiPlot 1980

  34. And a database Mitch and Lotus 123 in 1982

  35. Putting the PC on every desk The IBM PC

  36. And a spreadsheet on every computer 1995

  37. Business no longer uses Leonardo’s math TK!Solver by Bricklin and Frankston 1982 did not work out as well

  38. Spreadsheets are function machines, for… f(x)

  39. Solving dynamic business problems

  40. Analyzing data

  41. Visualizing information and concepts

  42. Modeling

  43. What if เกิดอะไรขึ้นถ้า ماذا لو 만약 如果 Hvad nu hvis Que faire si Cosasuccede se And asking Was ist, wenn ¿Quépasasi quod si Τι θα συμβεί αν どのような場合 מה היה קורה אילו Что делать, если E si Hvaðef

  44. In the year 2012 Mars Rover Curiosity arrived August 2012

  45. Our children are still taught to solve

  46. Leonardo’s math problems

  47. In a rigid sequence

  48. Considered outmoded in 1894 The Committee of Ten

  49. What if… We finally declare Leonardo’s Math Obsolete

  50. What if… students could learn the math of 21st century business
