this up somewhere. Unfortunately, it has a lot of truth. They call
this progress?
Teaching Math in 1950:
A logger sells a truckload of lumber for $100.
His cost of production is 4/5 of the price.
What is his profit?
Teaching Math in 1960:
A logger sells a truckload of lumber for $100.
His cost of production is 4/5 of the price, or $80.
What is his profit?
Teaching Math in 1970:
A logger exchanges a set "L" of lumber for a set "M" of money. The
cardinality of set "M" is 100. Each element is worth one dollar. Make 100
dots representing the elements of the set "M." The set "C," the cost of
production, contains 20 fewer points than set "M." Represent the set "C"
as a subset of set "M." Answer this question: What is the cardinality of
the set "P" of profits?
Teaching Math in 1980:
A logger sells a truckload of lumber for $100.
His cost of production is $80 and his profit is $20.
Your assignment:
Underline the number 20.
Teaching Math in 1990:
By cutting down beautiful forest trees, the logger makes $20. What do you

answering the question: How did the forest birds and squirrels feel as the
logger cut down their homes? There are no wrong answers.

His cost of production is $120.
How does Arthur Anderson determine that his profit margin is $60?
