This video is about the start learning mathematics. Here, we discuss the properties of the fractions. In particular, we construct the set Q, which is known as the rational numbers. This works analogously to the construction of the integers. We just have to look at another operation, which is the multiplication here.

I hope that this helps students, pupils and others.
