Indeed. Highlighting, as you would with a yellow marker.

No way! With kindergarten children, I could do, as I have done, real  
mathematics. This text is for the mathematical victims of a peculiar  
American institution called Developmental Education.

Here is the recipe for creating Developmental Students: You severely  
maim kindergarten children with a few well honed techniques, you then  
let them stew for 12 years in school and, "voilà" as my colleagues  
would say in English: They are ready for Developmental Education.

Well, that's for the cognoscenti.

The more modest title is:

 From Arithmetic to Differential Calculus in Three Semesters with a  
Chance of Passing the Sequence Significantly Higher Than the Current  
Pass Rate of Less Than One Quarter of One Percent in the Traditional  
Six Semester Sequence.


P.S. Since this is severely off topic, I would suggest that any  
response occur as "comments" on http://www.freemathtexts.org/Notes/  
(The list there is still at the conceptual stage.)
