The evolution of mathematics education during the last 30 years.
1960's
A peasant sells a bag of potatoes for $10. His costs amount to 4/5 of his
selling price. What is his profit?
1970's
A farmer sells a bag of potatoes for $10. His costs amount to 4/5 of his
selling price, i.e. $8. What is his profit?
1970's (New Math)
A farmer exchanges a set P of potatoes with a set M of money. The cardinality
of the set M is equal to $10 and each element of M is worth $1. Draw 10 big
dots representing the elements of M.
The set C of production costs is comprised of 2 big dots less than the set M.
Represent C as a subset of M and give the answer to the question: What is the
cardinality of the set of profits? (Draw everything in red).
1980's
A farmer sells a bag of potatoes for $10. His production costs are $8 and his
profit is $2. Underline the word "potatoes" and discuss with your classmates.
1990's

There's probably a "0" chance that you took a course in probability. :-)
A new benchmark has been released which accurately measures the speed
of any computer. The computer is pushed off the top of a building, and
speed calculated by multiplying by 32.2 fps squared.
The MIPS (Meaningless Index of Plumeting Speed) rating is the raw
value times the number of CPUs. This is called the FhallingStone
benchmark.
