Betti numbers are nonnegative integers that helps classifying topological spaces. Loosely speaking, the $n$th Betti number counts the number of $n$-dimensional holes. They are defined as ranks of homology groups. In this talk we will introduce them by looking at simplicial homology and focusing on many examples.
