What is the Unicode code point for the intersection symbol?

The intersection sign is U+2229 in the Unicode standard, used in set theory to show the elements shared by two sets.

What is the HTML entity for the intersection symbol?

Use ∩ or the numeric entity ∩ in HTML. Both render as ∩.

How do I type the intersection symbol in LaTeX?

Use \cap inside math mode, for example $A \cap B$, which renders as A ∩ B.

How do I type the intersection symbol on a Mac?

Open the Character Viewer with Control+Command+Space, search "intersection", then double-click the symbol to insert it. There is no direct Option key shortcut for this character.

How do I type the intersection symbol on Windows?

In Microsoft Word, type 2229 then press Alt+X to convert it to ∩. Outside Word, use the Character Map app or copy the symbol from a page like this one.

What does the intersection symbol mean?

It denotes the set of elements common to two sets: A ∩ B reads as "A intersect B" and contains only elements that belong to both A and B. The related union symbol, ∪, combines all elements from both sets instead.
