MATH 1324 deals with how to apply the techniques of algebra to
problems arising in business. To learn about these applications,
it is necessary that you recall how to use the basic algebraic
techniques you have already learned. We realize that you may have
forgotten some of this algebra, but you must review and relearn
it very quickly in MATH 1324. It is briefly explained in the first
two chapters of the book, but we cover that rather quickly--much
too quickly to provide you with a thorough review unless you remember
most of it before you start the course.
The following problems provide a quick review of this algebra. The answers are listed at the end. If you find that you cannot do at least 12 of them right now, you need to do one of two things before you attempt to take MATH 1324.
1. Get an algebra book and review these topics.
2. If you are unable (or don't have time) to learn these topics
by reviewing on your own, you need to take 1 or 2 algebra courses
to refresh your algebra skills. The appropriate courses at ACC
are Intermediate Algebra (MATD 0390) or Elementary and Intermediate
Algebra (MATH 0370 and MATD 0390).
