How to fix the “missing $ inserted” error in LaTeX?
When you encounter the “Missing $ inserted” error in LaTeX, it typically means that you are using math symbols outside of math mode.
To address this issue, you can follow the steps below:
- Check your document for any mathematical symbols. In LaTeX, use $ or () to enter math mode. Make sure you correctly use these commands where necessary for mathematical symbols.
For instance, if you want to insert a mathematical symbol in text, you can use the $ symbol to enclose it, like $x^2$.
- Check for missing closing math mode delimiters. If you have entered math mode, make sure to use the correct closing delimiter before ending the mathematical expression. For example, if you entered math mode using the $ symbol, ensure to use an additional $ symbol in the appropriate place to end the math mode.
- Check for errors when blindly copying and pasting mathematical symbols. Sometimes, errors can occur when copying mathematical symbols from elsewhere and pasting them into a LaTeX document. This may be due to invisible special characters or formatting errors in the copied content. In such cases, you can manually type the mathematical symbols to ensure the correct formatting.
If you are still unable to solve the problem, you may want to consider adding more context around the incorrect code and providing relevant code snippets when asking questions, so that others can better assist you.
