    There are many resources for our course material.  I am likely to most often be preparing from Finite Mathematics, Maki & Thompson, 4th edition, and the section numbers and titles come from there.  There are many books in the library at QA39.2.  There are some reasonable online books.  Here is what looks to me to be the best online choice at open staxx.  Here is another at lumen learning.

Course Goals
    "Finite Mathematics" means mathematics without calculus.  In fact, it is further without anything but linear algebra (algebra of lines).  We will look at sets as preparing us for probability study.  For the second half of the course we will consider linear algebra and see what applications we can find.  It's a gentle exploration, but sometimes we will be surprised what we can do without getting into much background. 

Learning Outcomes 
    Upon successful completion of Math 113 - Finite Mathematics for Social Sciences, students will be able to

    Upon successful completion of the R/ requirement, students will be able to

    Your grade in this course will be based upon your performance on various aspects.  The weight assigned to each is designated below:
                   Problem Sets (9)     40%    4% (now more) each, drop the lowest
                   Exams (3)                40%    10% (now more) each
                   Quizzes (4)              20%    5% each
                   Optional Final Exam 0-20% replaces half of each lesser individual exam

Problem Sets
    There will be eleven assignments.  Each assignment will constitute five exercises of your choosing from any source on the topics of the associated sections and five problems of my designation.  Assignments are due on the scheduled dates.  You are encouraged to consult with me outside of class on any questions toward completing the homework.  You are also encouraged to work together on homework assignments, but each must write up their own well-written solutions.  A good rule for this is it is encouraged to speak to each other about the problem, but you should not read each other's solutions.  A violation of this policy will result in a zero for the entire assignment and reporting to the Dean of Students for a violation of academic integrity.  Each assignment will be counted in the following manner:  the exercises will be checked for completeness and will be worth four points each if completed.  The problems will be scored out of four points each:
                 0 - missing question or plagiarised work 
                 1 - question copied
                 2 - partial question
                 3 - completed question (with some solution)
                 4 - completed question correctly and well-written
Each entire problem set will then be graded on a 90-80-70-60% (decile) scale.  Late items will not be accepted.  Solutions to the problems (not to exercises) will be posted at the time they are submitted.  Assignments will be returned on the following class day.  Because solutions will be provided, comments will be somewhat limited on individual papers, and late papers will not be accepted.  Please feel free to discuss any homework with me outside of class or during review.    The lowest problem set score will be dropped.

Solutions and Plagiarism
    There are plenty of places that one can find all kinds of solutions to problems in this class.  Reading them and not referencing them in your work is plagiarism, and will be reported as an academic integrity violation.  Reading them and referencing them is not quite plagiarism, but does undermine the intent of the problems.  Therefore, if you reference solutions you will receive 0 points, but you will *not* be reported for an academic integrity.  Simply - please do not read any solutions for problems in this class.  

    There will be short quizzes as scheduled, covering the material at the level of the exercises from the homework.  Quizzes will consist of routine questions, and will have limited opportunity for partial credit. Because quizzes will consist of routine questions, they will be graded on a decile scale.  There will be no makeup quizzes. 

    There will be four exams during the semester (the fourth will be on the day of the final exam) and a final exam during finals week.  If you must miss an exam, it is necessary that you contact me before the exam begins.  The bulk of the exam questions will involve problem solving.  Exams will be graded on a scale approximately (to be precisely determined by the content of each individual exam) given by 
        100 - 80%    A
          79 - 60%    B
          59 - 40%    C
          39 - 20%    D
       below 20%    E
For your interpretive convenience, I will also give you an exam grade converted into the decile scale.  The exams will be challenging and will require thought and creativity (like the problems).  They will not include filler questions (like the exercises) hence the full usage of the grading scale. 

Final Examination
    The final exam is optional.  It will contain questions from throughout the course.  If you earn a higher score on the final than any of the individual exams throughout the semester, the score on the final will replace half of the score on the individual exam. 

    Occasionally you will be given anonymous feedback forms.  Please use them to share any thoughts or concerns for how the course is running.  Remember, the sooner you tell me your concerns, the more I can do about them.  I have also created a web-site which accepts anonymous comments.  If we have not yet discussed this in class, please encourage me to create a class code.  This site may also be accessed via our course page on a link entitled anonymous feedback.  Of course, you are always welcome to approach me outside of class to discuss these issues as well.  

Disability Accommodations
    SUNY Geneseo will make reasonable accommodations for persons with documented physical, emotional or learning disabilities.  Students should consult with the Office of Disability Services (105D Erwin) and their individual faculty regarding any needed accommodations as early as possible in the semester.

Religious Holidays
    It is my policy to give students who miss class because of observance of religious holidays the opportunity to make up missed work.  You are responsible for notifying me no later than January 31 of plans to observe the holiday.
