How to Write Not Equal in LaTeX

Simple steps to create amazing results

Use the Basic \neq Command

Simply type \neq in your LaTeX document between dollar signs for inline math ($\neq$) or in math mode. This produces the standard ≠ symbol and works in all LaTeX environments.

Choose Your Math Environment

Decide whether you need inline math mode ($x \neq y$) for text or display math mode ($$x \neq y$$) for standalone equations. Both support the not equal symbol seamlessly.

Compile and Verify

Compile your LaTeX document to see the not equal symbol rendered correctly. If issues arise, ensure you're in math mode and the command is spelled correctly.

LaTeX Not Equal Symbol Methods

Powerful capabilities at your fingertips

Standard \neq Command

The most common and recommended method. Use \neq to produce the ≠ symbol in any mathematical expression or equation.

Alternative \ne Command

A shorter alternative that produces the same result. Type \ne instead of \neq for identical output in your LaTeX documents.

Negation with \not

Use \not= to create a not equal sign by negating the equals symbol. This method works with other operators too for versatile negation.

Package-Specific Symbols

Advanced packages like amssymb offer additional variations and styling options for inequality symbols in specialized mathematical contexts.

Works in All Math Modes

Compatible with inline math, display math, equation environments, align environments, and all standard LaTeX mathematical contexts.

No Extra Packages Needed

The \neq and \ne commands work out of the box in standard LaTeX without requiring any additional package imports.

Frequently Asked Questions

Everything you need to know

How do I write the not equal sign in LaTeX?

To write the not equal sign in LaTeX, use the command \neq. This will produce the ≠ symbol.

What's the difference between \neq and \ne in LaTeX?

There is no difference in output. Both \neq and \ne produce the same not equal symbol (≠). \neq is more commonly used, while \ne is a shorter alternative.

Can I use LaTeX on Overleaf?

Yes, Overleaf is a popular online LaTeX editor that supports all LaTeX commands, including those for not equal and other mathematical symbols.

What are some common LaTeX symbols?

Common LaTeX symbols include not equal (\neq), less than (\lt), greater than or equal to (\geq), and many others. Our guide provides detailed instructions for each.

Do I need to import packages to use \neq?

No, the \neq command is available in standard LaTeX without any additional packages. However, packages like amssymb provide additional mathematical symbols.

Can I use not equal in text mode?

The \neq command must be used within math mode. Use $\neq$ for inline text or $$\neq$$ for display mode. It won't work in plain text mode.
