This ‘original cat book’ (below) was filled out
an entire First Course in Algebra
If you go through that entire Algebra I course,
then you're guaranteed
to get everything from
the book belowplus lots more!
However, if you're trying to use my higher-level materials (e.g.,
having gone through the
Algebra I course
then I highly recommend that you read this original cat book.
