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.
