This article summary is from the Wall Street Journal online edition on June 10, 2013:

**SoftBank said it had agreed with Sprint Nextel to raise its offer for the U.S. wireless carrier by $1.5 billion to $21.6 billion from $20.1 billion.**

What does the summary say about the state of mathematical literacy in the United States when a publication like the Wall Street Journal that deals with high finance is compelled to include all three numbers of the simple equation C = A – B? Perhaps this reminds you of the joke about the evolution of teaching math since the 1950s:

1. Teaching Math In 1950s

A logger sells a truckload of lumber for $100. His cost of production is 4/5 of the price. What is his profit?

2. Teaching Math In 1960s

3. Teaching Math In 1970s

4. Teaching Math In 1980s

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.

5. Teaching Math In 1990s

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.

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, and if you feel like crying, it’s ok).
