MATH 125: Linear Algebra for Business




Introduction to systems of linear equations, matrices, and vector spaces, with emphasis on business applications.

Success in Math 125 does requires a lot of work, many hours of study and problem solving, and your active involvement in learning, both inside and outside the classroom. We have designed our course with the aim of helping you stay constantly involved with the course and the material, and within easy reach of some of your best resources: your instructor, your teaching assistants, and your colleagues.

Math 125 requires a custom textbook with a MyMathLab Access Code. The required textbook is Math 125 2nd custom edition for UIC, available in our bookstore only. Optional to the student is to just purchase access to MyMathLab.


Math 125 requires a custom textbook with a MyMathLab Access Code. The required textbook is Math 125 2nd custom edition for UIC, available in our bookstore only. Optional to the student is to just purchase access to MyMathLab.

Regardless of the option chosen by the student, MyMathLab Access is required, grades will not be given to students without full semester access activation.

We will cover chapters 1 - 4 and 8 - 9. You are expected to read the textbook before the classroom discussion of each topic, as indicated on the schedule of homework and reading assignments.

A graphing calculator such as TI-83, TI-83+, TI-84 or TI-84+ is REQUIRED . You may use it on exams, however, you will still be required to show work in most cases. Models such as the TI-nSpire are not recommended, nor are Casio and other manufacturers. The TI-83/84 model will be demonstrated in class.


MATH 090 or a grade of C or better in MATH 110 or appropriate performance on the UIC mathematics placement test.


The class meets weekly for three lectures on Monday, Wednesday, and Friday and two discussion sessions on Tuesday and Thursday.

Attendance will be taken daily in lecture and discussion sessions.

Discussion time will be devoted to problem solving, worksheets, and group work.

MyMathLab (online) homework is assigned for each section and is due the following lecture day at 11:59 P.M. Most lecture days will have online homework due that day, with only a few exceptions.

Written homework is assigned once per week (see Homework schedule). It will be submitted on Gradescope each Thursday by 11:59 P.M.


Cell Phones

You may not use your phone during lecture and discussion sessions for any reason. We ask that you stay focused on the material while attending class. If this becomes a problem, your instructor or teaching assistant will ask you to leave the room.


The course grade is based on the following categories with the point percentages associated to each. Students are expected to be present for all exams. Makeup exams will only be given in case of a verifiable emergency or a formal request by the UIC athletic department. Do not schedule travel on an exam date.

Attendance See Attendance Policy
Written Homework 10%
MyMathLab Homework 15%
Discussion Session 10%
Test 1 20%
Test 2 20%
Final Exam 25%

The grading scale is:

Percentage Grade
87-100 A
75-86 B
60-74 C
45-59 D
0-44 F

Final grades in general are not curved, however, the department reserves the right to be more lenient than this.

The midterm grades will follow the same percentage cut-offs as for the final course grades, but with the following contributions:

Exam Ave 70%
Written HW Ave 10%
Discussion Ave 10%
MyMathLab Ave 10%
Total 100%


Lectures and discussion/problem sessions: As explained in the course description, in order to successfully complete the course, your active involvement in learning is essential. Therefore, a serious commitment on your part to attend both the lectures and the discussion/problem sessions is a basic requirement of that. Attendance in the course will be taken both in lecture and in discussion sections starting with week 3.

A percentage of below 75% in lecture, or a percentage of below 75% in discussion will result in a drop of one letter grade for the course as a consequence. Below 50% attendance in either one of these categories will result in an automatic F for the course.

Appeals: Students that know ahead of time that they have an existing or potential conflict with the class must inform their instructor in the first two weeks of the semester using the absence appeals form.

Furthermore, students can appeal during week 9 and 10, as well as week 14 and 15 to their instructor using the appeals form provided below. Note: no appeals will be accepted after the final exam or at any other time!

In cases when the instructor cannot determine whether or not the reason is compelling, the instructor will forward the appeal to the director of undergraduate studies, who will decide.

Cheating the Attendance Policy: Trying to cheat the attendance policy is unacceptable, and the consequence for cheating will be severe. Examples of trying to cheat the attendance policy include (but are not limited to) signing in to receive credit when you are not present, signing a classmate in who is not present, or providing false documentation of an absence. The first offense of cheating will result in an automatic one letter grade deduction from your final grade, and the second offense will result in an automatic F in the course.


Written Homework assignments are posted in Blackboard and will be due on the specified date (listed on the homework itself). No late homework will be accepted. Written homework will be submitted on Gradescope. You are strongly encouraged to work together with a group of colleagues on these (and any) homework problems, but you must write up the solutions by yourself!

You will have to scan your solutions and submit them to the online homework system before the deadline. The instructions on how to do that are available on the Blackboard site.

Written homework problems will be graded in full, and just an answer will not earn any credit. You should pay attention to the feedback given on each graded homework, since the midterms and the final exam will be graded in a very similar way.

Daily MyMathLab Homework is due the day of the following lecture day at 11:59 PM, which you can access through the Blackboard link. MyMathLab is a tool to provide instant feedback to problems that cover the basic material of the course.


During discussion, you will be given worksheets and group work. One will be graded per week, except for weeks with exams. Please also read the required attendance policy.


Students who know ahead of time that they have an existing or potential exam conflict with the exam times must inform their instructor in the first two weeks of the semester. There will be two evening exams (see the Exams link above for their dates). The exams will be from 6-7:30pm. The final exam schedule will be announced soon, and will be a cumulative exam. With all exams, make-ups will not be given except under extreme circumstances.

Policy on re-grading midterm exams and homework: After receiving your graded midterm exam or a homework, you are recommended to review the grading. If you think that your work has been misgraded, you may put in a regrade request via Gradescope. You must explain clearly why you think your work deserves more points and what grading mistakes have been made. Requests without justifications will not be honored. We will correct the grading, if justified. All requests to review the grading of exams or homework must be made within one week from the day when the link to your graded homework or exam has been sent to you via Gradescope, and within one day for the final exam.


There will be no make-up worksheets given, but the lowest two in each category (Written Homework, Discussion work, and MyMathLab Homework) will be dropped.

Students are expected to be present for all exams. Do not schedule travel on an exam date. The Makeup Policy can only be applied for exams in case of a verifiable emergency or a formal request by the UIC atheletic department. Students are expected to obtain prior permission for an absence from the instructor. In all cases, the student must provide written documentation when attempting to secure this permission. Documentation from the student health service, or its equivalent from a doctor or hospital, etc. should be given to your instructor.
