The average price of a case of beer — which contains around three gallons — is still $20, putting the ultra-premium fuel at approximately $6.66 per gallon. Given the sign comes from Alabama, the numeric value may be precisely why they didn’t bother to do that part of the math…

I once tried to pay for my coffee at Dunkin Donuts with two Kennedy fifty-cent coins. I say tried because they told me, “We don’t accept foreign currency.”

I didn’t fail Biology or Math when I was in school, and thus, never fathered any children. I will admit, however, that I did fail English once, which is a bit odd to me, considering it is my first language…

Just like I’ve always said — pie are not squared. They are round.

Last week I purchased a burger at Burger King for $1.58. The countergirl took my $2 and I was digging for my change when I pulled 8 cents from my pocket and gave it to her. She stood there, holding the nickel and three 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 it has to do with the evolution of teaching math since the 1950s…

• 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 ?

• Teaching Math In 1960s:
  

  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 1970s:
  

  A logger sells a truckload of lumber for $100. His cost of production is $80.

  Did he make a profit?

• 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.

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

• Teaching Math In 2009:
  

  Un hachero vende una carretada de maderapara $100. El costo de la producciones es $80.

  ¿Cuanto dinero ha hecho?

• Teaching Math In 2010:
  

  Who cares, just steal the lumber from your rich neighbor’s property. He won’t have a gun to stop you, and the President says it’s OK, anyway, because it’s redistributing wealth.

If you can’t do math, you have no business working a cash register.
