- What is the meaning of $(\\mathbb{Z} n \\mathbb{Z})^{\\times}$?
$ (\Bbb Z n\Bbb Z)^\times$ often means the group of units It consists of all the elements in $\Bbb Z n \Bbb Z$ that have an inverse These elements form a group with multiplication Example: $\Bbb Z 4\Bbb Z=\ {0,1,2,3\}$ form a group with respect to addition $\langle\Bbb Z 4\Bbb Z, +\rangle$ To form a group with multiplication, with the same set, we need to throw out some elements $2\in\Bbb

- What does versus mean in the context of a graph?
I would agree with the rule " [dependent] versus [independent] " The word "versus" can mean "compared with," and it more frequently makes sense to compare a dependent value with its associated independent value, because well, the independent variable doesn't really "care" about the existence of the dependent variable, but the converse relationship is by definition
