The Element-of Symbol (∈) indicates membership within a set, while the Not-an-Element-of Symbol (∉) denotes non-membership or exclusion from a set.

The Element-of Symbol (∈) has various applications:

Mathematics: Fundamental in set theory to represent the membership of an element within a set.
Computer Science: Used in algorithms and pseudocode to check if an item belongs to a collection.
Logic: Utilized in logical expressions to depict relationships among sets.

Windows: For some keyboards, hold down the Alt key and type 8712 on the numeric keypad, then release the Alt key.
Mac: This might vary based on specific applications and fonts.
Linux: Press Ctrl + Shift + u, then type 2208 and press Enter.
HTML: Use the named entity ∈ or the numeric entity ∈.
LaTeX: To type the Element-of Symbol in LaTeX, use the command \in.
