## Module aim (aims)

• to teach students to recognize the type of problems that require numerical techniques for their solution
• to show them some examples of the error propagation that can occur when numerical methods are applied
• to teach the students to approximate the solution to some problems that cannot be solved exactly.
• students are taught to use the numerical analysis methods in MS Excel.

## Pre-requisites in terms of knowledge, skills and social competences (where relevant)

The course is dedicated to students with some knowledge of mathematics and MS Excel.
