Welcome to Math in Society
Mathematics 107 is a college-level mathematics course for liberal arts majors. Interesting
and practical topics showcase the relevance of mathematics.
The course fulfills the QSR requirement for the AA degree. The prerequisite for the course
is Intermediate Algebra (Mathematics 098).
Topics include logic, statistics, trigonometry, finance, algebraic models, and number systems.
In order to make learning the subject easier for yourself and all the students in the class,
please
• ask questions when something is not clear
• attend the class regularly
• work the homework problems thoroughly. It’s not possible to become proficient in
mathematics without doing it yourself. Give yourself an hour or two for each hour in
class to work through each day’s assignment
• browse through the material for each day before class. We’ll usually discuss two or
three sections of the book each evening
• take advantage of the Math Learning Center (ED 1845) for tutoring help. It’s open
every day! or visit me during my office hours.
• be respectful of others in the class.
• refrain from talking with neighbors unless we’re working problems in class
In my commitment to student learning I want to support all students. If you have a disability that will affect your performance in this class please let me know. Students with
disabilities are encouraged to use Disability Services for support in implementing reasonable
accommodations for their disabilities.
I’ll spend most of the class time explaining the concepts and presenting examples showing
how the concepts are applied. I welcome questions at any time. There will be portions of
class time where you get a chance to solve some problems.
Keeping up with the new concepts through homework exercises is essential to success in the
course, and I will periodically ask you to hand in your assignments. There will be three
tests during the quarter and a comprehensive final exam. There will be an opportunity to
make-up one of the three tests by the way I score the final exam. I look at each section of
the comprehensive final (a test one part, a test two part , and a test three part) and look to
see on which section you have improved the most. If you have, for example, improved the
most on the test two part of the final exam, then the score on the test two portion of the
final replaces your original test two score. Of course, if the final exam scores are all lower,
your original test scores are left unchanged.
what you’ll need
book: “The Mathematical Palette” , 3rd edition, by Staszkow and Bradshaw, Thomson/BrooksCole Publishing Co.
a scientific calculator
prerequisite: completion of Intermediate Algebra (Mathematics 098) or equivalent with a
grade of 2.0 or better.
please turn off the sound on all cellphones, pagers, etc. during class
grades
Each of the three tests and the final exam will be worth 100 points, and the quizzes, homework, and other assignments and projects will count as a smaller number of points. The
course grade is based on a percentage which may be calculated at any time. Add together
all your points. Then divide by the sum of the possible points. Multiply by 100 for the
course percentage. Course grades are then determined by the following scale:
93% and up 3.9 or 4.0*
90%
3.8
80%
3.0
70%
2.0
60%
1.0
50%
0.7
under 50%
0.0 or NC
* A course percentage of at least 93%,
and a score of at least 90% on each test
earns a 4.0.
Other grades are linearly interpolated. For example, a score of 85% corresponds to a grade
of 3.4.
