>>>1970 (New Math): A logger exchanges a set L of lumber for a set M of money.
>>> The cardinality of set M is 100 and each element is worth a dollar. Make a

>>>1980: A logger sells a truckload of lumber for $ 100. His cost of
>>>production is $80 and his profit is $20. Your assignment is to underline
>>>the number 20.

>>>1990 (Outcomes-based destreamed integrated Math): By cutting down beautiful
>>>forest trees, an environmentally ignorant logger makes a profit of $20.
