“Welcome to Introduction to Numerical Mathematics. This is designed to give you part of the mathematical foundations needed to work in computer science in any of its strands, from business to visual digital arts, music, games. At any stage of the problem solving and modelling stage you will require numerical and computational tools. We get you started in binary and other number bases, some tools to make sense of sequences of numbers, how to represent space numerical using coordinates, how to study variations of quantities via functions and their graphs. For this we prepared computing and everyday life problems for you to solve using these tools, from sending secret messages to designing computer graphics.

The content is very interesting and the professor is amazing. But, the quality of the examinations could use some perfecting, although they are challenging and relevant which is a very good thing!
por AS23 de Mar de 2020
It was challenging and at some parts a little bit ambiguous but I think the material was good and the teacher's passionate and funny personality made it an enjoyable experience.
por GL2 de Mai de 2019
still errors in quizzes after notification in beta-test. No-one from staff replies to comments or forums. I really want to give it 3.5, not 4
por AJ30 de Mai de 2020
There are problems with some of the quizzes and were extremely frustrating, but I had positive learning experience with Dr Sara Santos
