$\underline{ \pink{ Difference \: of \: sets : }}$

$\blue{ Let \: A \: and \: B \: are \: two \: sets ,}\\\blue{ the \: difference \: of \: A \: and \: B \: is }\\\blue{ the \: set \: of \: all \: those \: elements \: of }\\\blue{ A \: which \:do \: not \: belong \: to \: B , }$

$i.e., \pink{ A - B = \{ x : x \in A \: and \: x \cancel { \in } B \} }$

$\pink{ B - A = \{ x : x \in B\: and \: x \cancel { \in } A \} }$
