**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 the e-learning tool for Mathematics developed by Prof. Dr. Enrico De Giorgi in collaboration with Taskbase for students enrolled in the first year of the Bachelor programs (Major Economics, Major Business and Major Law) at the University of St. Gallen.

**e-maths.ch** summarises the **theory** and the most important mathematical techniques as described in the book “Mathematics”.

**e-maths.ch** allows students to access more than 1200 **questions **and detailed** solutions** on the topics of Mathematics A and Mathematics B. Questions are chosen for each user by a recommender based on past performance.

**e-maths.ch** supports students’ learning process since it provides constant and immediate **feedback** on their progresses.
