You may consider the relations of equality `=` as a equivalence relation over the set of integer numbers Z.

Notice that the equality is **reflexive** because for any `x in Z` , `x=x` holds.

The equality relation is also **symmetric** because `x=y` implies `y=x` .

The equality relation is **transitive** since if `x=y` and `y=z` yields `x = z` .

**Hence, the relation of equality is an equivalence relation over `Z` .**
