In LaTeX, when working within the math mode environment, writing text as you normally would is not possible. This is because spaces are ignored, and the letters are displayed in an italicized font. However, you can include text within math expressions using the \textrm{} command. If you're using the amsmath package, you can achieve the same result with the \text{} command. Remember to enclose any text or spaces within curly braces to ensure their proper recognition within the math mode environment.

In LaTeX, text within the math mode environment cannot be written as usual because spaces are ignored and letters are displayed in italics.

### Example

This LaTeX example demonstrates how to include text within a mathematical expression using the \textrm{} command.

\documentclass{article}
\begin{document}
Test Text $a^{2} + b^{2} \textrm{ Text within math mode } = c^{2}$
\end{document}


This LaTeX code snippet showcases how to incorporate regular text within a mathematical equation. The expression a2 + b2 = c2 represents the Pythagorean theorem, where a and b are the lengths of the two shorter sides of a right triangle, and c is the length of the hypotenuse. The \textrm{} command is used to ensure that the text "Text within math mode" appears in regular (non-italicized) font within the mathematical context. This is particularly useful when you want to include descriptive text or labels within mathematical formulas while maintaining proper formatting.

### Example 2

This LaTeX example demonstrates how to include text within a mathematical expression using the \text{} command from the amsmath package.

\documentclass{article}
\usepackage{amsmath}
\begin{document}
Test Text $a^{2} + b^{2} \text{ Text within math mode } = c^{2}$
\end{document}


This LaTeX code snippet illustrates how to incorporate descriptive text within a mathematical equation. The expression a2 + b2 = c2 represents the Pythagorean theorem, where a and b are the lengths of the two shorter sides of a right triangle, and c is the length of the hypotenuse. The \text{} command allows you to insert plain text "Text within math mode" within the mathematical context without affecting the formatting of the surrounding equation. This can be helpful for providing explanations or annotations within mathematical formulas.

It is recommended to use spaces within curly braces to ensure their effect within the math mode environment.
