comment Help on mathematical notation and formalisation for the following description

comment Set notation “element-of” multiple sets
DylanMoreland: agree, @PatrickDaSilva:thanks. A bit newbie to mathematical notation and formalisation from a coder background. I was wondering is there any books on such topics or good material to learn?
