An Ordered Listing
of the Lessons
The Purplemath lessons
have been written so that they may be studied in whatever manner
the student finds most useful. Different textbooks cover different topics
in different orders. The Purplemath lessons try not to assume any fixed
ordering of topics, so that any student, regardless of the text he is
using, may benefit.
While the structure of
the Purplemath lessons lends itself to many topical orderings, the following
is one possible lesson sequence. Follow this sequence by working down
the left-hand, then middle, and then right-hand columns of each section,
proceeding through the sections from the top of the page to the bottom.

Please note that the above
is only one of many equally-valid lesson orderings, and should not be
regarded as "the" lesson sequence. You may benefit as much or
more by studying the lessons in a different order. Let your own needs
be the final judge.
