Reasonable Arithmetic & Algebra (RAA) is a standalone version of Part I of A2DC, that is the prequel to Lagrange Differential Calculus, meant to parallel the more usual "developmental" courses. The main difference between RAA and Part I of A2DC is the de-emphasis of arithmetic functions and approximations.  I believe, though, that this de-emphasis results in a contents architecture that is weaker than that of Part I of A2DC and that the latter could in fact also be used as a standalone since there is no prerequisite either.

NOTE. While the contents of RAA might appear to be much the same as those of RBA, in addition to de-emphasizing arithmetic functions and approximations, Part I - Introduction to Arithmetic of RBA develops the necessary ideas only in the context of counting number-phrases and takes decimal number-phrases for granted. The contents of both RAA and RBA were cut back compared to those of Part I of A2DC because they had to fit the schedule of existing courses at my school. It should be fairly easy to adapt them to more generous schedules.
