| Nuclear Duck Hunter ![]() | Post; Evolution Of MathCan anyone identify with any of these stages of evolution? Evolution of Math Last week I purchased a burger and fries for $3.58. The counter girl took my $4.00 and I pulled 8 cents from my pocket and gave it to her. She stood there, holding the nickel and 3 pennies. While looking at the screen on her register, I sensed her discomfort and tried to tell her to just give me two quarters, but she hailed the manager for help. While he tried to explain the transaction to her, she stood there and cried. Why do I tell you this? Because of the evolution in teaching math since the 1950s. 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 sells a truckload of lumber for $100. His cost of production is $80. Did he make a profit? 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 A logger cuts down a beautiful forest because he is selfish and inconsiderate and cares nothing for the habitat of animals or the preservation of our woodlands. He does this so he can make a profit of $20. What do you think of this way of making a living? Topic for class participation after answering the question: How did the birds and squirrels feel as the logger cut down their homes? (There are no wrong answers.) Teaching Math In 2006 Un ranchero vende una carretera de madera para $100. La cuesto de su produccion era $80. Cuantas tortillas se puede comprar?

| Tribunus Laticlavius | horrible, yet sadly true i have down that, my total was some odd sense, so i gave the girl some change to make it so it would be 3 quarters, she didnt know what to do, i told her just give me 3 quarters, she calls the manager for help and they end up needing a calculator

| Tribuni Angusticlavii | it really is sad that so many people cant do basic math anymore without a calculator. the things were designed to help with hard math equations.

| Milforum Swamp Dweller | Jesus H. Christ, I took a practice GRE exam (college graduate exit exam) and scored: 490/500 in english 490/500 in math Analytical writing wasn't graded, but you need 1000 out of 1600 points to pass. I'm a sophomore, and I'd already learned everything on that practice test.
