$A\times B$ is a set of ordered pairs, where each element of A is mapped to each element of B. The element from A appears as the first element in the ordered pair.
$\ \ \ grape\rightarrow\ \ |\overset\rightarrow\ jam$
$\ \ \ \ \ \ \ \ \ \ \ \ \,\ \ \ \ \ \ \ \ |\overset\rightarrow\ juice$
$\ \ \ apple\rightarrow\ \ |\overset\rightarrow\ jam$
$\ \ \ \ \ \ \ \ \ \ \ \ \,\ \ \ \ \ \ \ \ |\overset\rightarrow\ juice$
$\ \ \ orange\rightarrow\ \ |\overset\rightarrow\ jam$
$\ \ \ \ \ \ \ \ \ \ \,\ \ \ \ \,\ \ \ \ \ \ \ \ |\overset\rightarrow\ juice$
