\neq is the inequality sign. The \not prefix slashes any relation symbol, so \not\equiv, \not\subset and so on also work, though amssymb provides nicer dedicated versions for the common ones.
All ways to write it
| Command | Use | Package | Copy |
|---|---|---|---|
\neq | also \ne | none | |
\not= | generic negation slash | none |
Example
a \neq b \implies a - b \neq 0A simple inequality statement.
Questions
How do I negate other symbols?
Put \not in front: \not\in, \not\subset, \not\equiv. amssymb has \notin, \nsubseteq, \nequiv with better spacing.
