This is a new entry about math, or maths, or mathematics, whatever you prefer. I usually use math, but maths is the same mainly in UK. It does not matter, both are great.

I have already talked about the importance of mathematics in another entry. Today, returning to the subject, I would like to talk about this matter again, in a more direct way.

The reason is a recent conversation with a mathematics professional, a teacher who is truly desperate due to the very low level of mathematics that we have in Europe (at least). A serious problem, since the lack of knowledge of mathematics entails many problems for students, not only in their studies, but in life in general as well.
