\land and \wedge print the same ∧. Use \land in logic so the source reads as 'and', and \wedge for the exterior product. For the ampersand character, escape it as \&, because a bare & is the column separator in align environments and tables.
All ways to write it
| Command | Use | Package | Copy |
|---|---|---|---|
\land | logical and | none | |
\wedge | same glyph, used for the wedge product | none | |
\lor | logical or, ∨ (also \vee) | none | |
\lnot | logical not, ¬ (also \neg) | none | |
\& | the ampersand character itself | none |
Example
(p \land q) \implies pIf p and q are both true, then p is true.
Questions
What is the difference between \land and \wedge?
None in the output, both print ∧. \land says what you mean in logic; \wedge is the usual name for the exterior product.
How do I type & in LaTeX?
Write \&. A bare & separates columns in tables and in align, so it causes an error or a misaligned line anywhere else.
What are the or and not symbols?
\lor (or \vee) prints ∨, and \lnot (or \neg) prints ¬. All of them work in KaTeX.

Using logical and in Confluence
Confluence Cloud has no built-in LaTeX. With LaTeX Math for Confluence you add a math macro to any page, type \land and it renders inline or as a block, with a live preview while you edit. Every command on this page renders there without extra packages.
