The statement "Tia likes red" is written (Tia, red).

The statement "Dani likes the color blue" is written (Dani, blue).

The set of sequential pairs for this relationship is written: {(Eva,
red), (Roni,
black), (Tia, red), (Dani, blue)}.
So, the relation between two sets, for example set A and set B, can
be expressed as an ordered pair (x, y) with x A and y B.

c) Cartesian diagrams

The relationship in the picture above can be expressed in a

Cartesius diagram. The members of set A as the first set are

placed on the horizontal axis and the members of set B on the

vertical axis. Each member of assembly A paired with a

member of assembly B, is marked with a period (•). For more

details, take a look at the Cartesius diagram showing the

following "color -loving" relationship.
