**Quantitative methods provide the foundation for many of the theoretical ****advancements of modern economics.**

Nowadays mathematical tools have become an important prerequisite for all those who want to understand the economic and business literature. Students of economics and business are required to achieve a solid understanding of mathematics. This includes mathematical tools such as infinitesimal calculus for functions of one or several variables, optimization with and without constraints, linear algebra and difference equations. Mathematics is also a way to logically structure arguments in order to obtain new hypotheses or statements to be tested on real data.

**e-maths.ch** is an e-learning tool for Mathematics developed by Prof. Dr. Enrico De Giorgi in collaboration with edTechLab for students enrolled in the Assessment year (first year of the Bachelor program) at the University of St. Gallen.

**e-maths.ch** allows students to access more than 600 multiple choice questions on the topics of the Assessment lectures Mathematics A and Mathematics B held at the University of St. Gallen.

**e-maths.ch** supports students’ learning process since it provides constant and immediate feedbacks on their progresses. Students can also access detailed solutions with references to the book “Mathematics”, where the necessary mathematical techniques are presented and discussed.

**e-maths.ch** complements, but does not substitute the exercise booklets “Mathematics A” and “Mathematics B” accompanying the book “Mathematics” and the weekly exercise sessions offered to Assessment students at the University of St. Gallen.
