Math Teaching--------------------------------------------------------------------------------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 subset of set "M" and answer the following 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 think of this way of making a living? Topic for class participation after answering the question: How did the forest birds and squirrels "feel" as the logger cut down the trees? There are no wrong answers.Teaching Math in 2000: A logger sells a truckload of lumber for $100. His cost of production is $120. How does Arthur Andersen determine that his profit margin is $60?Teaching Math in 2010: El hachero vende un camion carga por $100. La cuesta de productiones....

Teaching Math in 2020:A biotechnology concern grows solid-plate cellulose impregnated with genetically engineered lignin. The fixed costs of producing 1 ton of cellulose are floored at 1,000 USD and increase linearly at 100 USD per kg in addition to to the base charge. The government prescribed resale value is 130 USD per ton. How much would you have to bid on eBay in order to still make a profit?Teaching Math in 2030:The global nanotechnology conglomerate "Nanosoft" has a monopoly on all polymer structures used in construction. Their cost of production is 0 NEUROs, as the robots assemble themselves and retrieve the necessary base resources from the air and sunlight.How much does Nanosoft have to charge to finance it's ongoing military involvment in the Alpha Sector?Teaching Math in 2040:M(P(W([%X]))) := 34.01234 X == ???

How much firewood do you have to collect to survive the coming nuclear winter?

Teaching Math in 2070:There was this "thing" called "lumber" in the old planet Earth. It was mainly used for making fire by the antique human race. We Cyborgs not need that type of things; that why we enslaved the last 2 human, make them reproduced (fascitinating enough, those humans can't count..but they really multiply themselves!!); practiced some bioengineering on their children and created our superior race.Teaching Math in 2080:In the begginings there was chaos...
