Math Review

Wagner's courses in microeconomics, statistics and finance require knowledge and skills in basic math. Instructors will not spend time reviewing basic math in class; instead it is assumed that students have this understanding before beginning the course. Students who have not used math skills or completed a math-related course for some time are strongly encouraged to follow the step-by-step process below to prepare for quantitative coursework at Wagner.

A confident understanding of the topic areas below will allow students to focus on the new material that will be presented in quantitative classes each week.

In addition, students may find it helpful to visit the resources below whenever they need to brush up on a basic math topic.

Steps, Resources and Helpful Tips:

Step 1:  Review Relevant Topics

Step 2:  Practice Problem Sets

Step 3:  Review Video Resources

Tips for Success

Step 1:  Review Topics

Students need to be knowledgeable in all of the Review Topics below before beginning Wagner core quantitative coursework.

Step 2: Practice Problems

This section provides practice problems and answers for each of the sections in the Review Topics above. Students should complete the practice problems at the links below to refresh quantitative skills and build confidence in basic topics.

Step 3: Video and Online Media Resources

Some students may find it helpful to review topics and problems via teaching videos and slides found on the web. The following media resources may be helpful for students needing additional tutorials, or for whom learning via more visual instruction is helpful.

Fractions: Click on the Basic Mathematics and then the Fractions link for practice problems with video solutions on adding, subtracting, multiplying and dividing fractions.

Percents: Click on the Basic Mathematics and then the Percent link for practice problems with video solutions on percents.

Ratios: Click on the Basic Mathematics and then the Ratios link for practice problems with video solutions on ratios.

Proportions: Click on the Basic Mathematics and then the Proportions link for practice problems with video solutions on proportions.

Tips for Success

1. Students who found the Assessment Exam challenging, or know they need additional review after reviewing the topics and resources above, should enroll in the three-day non-credit Math Review Session (NONCR-GP 0906). The instructor for the Math Review Session will guide students through the Review Topics outlined above. The Session will also provide an opportunity to ask questions and to see direct applications of these topics for the quantitative core courses at Wagner.

2. Block time each week to not only complete homework, but to also attend tutoring sessions, to complete suggested problems for class, and for meeting with a study group.

  1. Take advantage of Wagner’s free tutoring support. Learn more about tutoring resources and the weekly tutoring schedule at Wagner here.
  2. Review and complete the practice problems outlined on these webpages, more than once, and complete any suggested problems found in course syllabi.
  3. Create a study group with classmates early in the semester. Study groups often meet each week to review problems and talk through course concepts.

3. Act early! After following the tips outlined above, students that are still struggling in a quantitative course should visit their instructor or teaching assistant early in the semester to discuss the problem areas. Office hours will be posted on the relevant course Blackboard site, or at the teaching assistants and faculty webpages.
