This article aims to show you the simplest and easiest way to write the <\/em>equal or not equal symbol in LaTeX<\/em>.<\/em><\/p>\n\n\n\n

A very common symbol used in mathematics and computer programming, with many more uses in spelling, linguistics and chemistry. Today you will learn how to insert it in your LaTeX document.<\/p>\n\n\n\n

Equal or not Equal Symbols<\/strong><\/h2>\n\n\n\n

Either called equal sign<\/strong>, equality sign<\/strong>, or equal symbol<\/strong>, is primarily used in mathematics to indicate an equality in a well-defined context, let\u2019s say for example that two things are equivalent between them. It is represented by two horizontal parallel lines that place between the values,<\/p>\n\n\n

\n
\"Equal

Usually in math we used the equal sign in equations to denote that two things are equals. We can also call this equality, a relation between two values.<\/p>\n\n\n

\n
\"Equal
Left side equals the right side<\/figcaption><\/figure><\/div>\n\n\n

In case the equality is false -the two things are not equivalent- we used the not equal symbol\/sign, it looks like the equal sign but instead of only two horizontal lines, it has a diagonal slash between the two lines.<\/p>\n\n\n

Equal or not Equal Symbol in LaTeX<\/strong><\/h2>\n\n\n\n

To write the equal symbol in LaTeX you don\u2019t need any command, it is already written in your keyboard, using the \u201c=\u201d you get the desired symbol. Either in math mode or text mode, it works the same.<\/p>\n\n\n

\n\\documentclass{article}\n\\begin{document}\n\\begin{center}\n\u00a0 \u00a0 Equal symbol in text mode: 1=1 \\\\\n\u00a0 \u00a0 Equal symbol in math mode: $a=b$\n\\end{center}\n\\end{document}\n<\/pre><\/div>\n\n
\n
\"Equal
Equal symbol in text and math mode<\/figcaption><\/figure><\/div>\n\n\n
Note: notice the difference in spacing between math mode and text mode.<\/p>\n\n\n\n
Now regarding the not equal symbol, this time we don\u2019t have such luck. The main difference between the \u201cnot equal to<\/strong>\u201d and the \u201cequal to<\/strong>\u201d symbols is the former requires math mode, the latter does not.<\/p>\n\n\n\n
To write it in LaTeX we have two commands we can use, either \\neq<\/strong> or \\ne<\/strong>, both work fine and generate the same symbol. <\/p>\n\n\n
\n\\documentclass{article}\n\\begin{document}\n\\begin{center}\n\u00a0 \u00a0 Not equal symbol \\verb|\\neq|: $x \\neq y$ %two variables are not equal \\\\\n\u00a0 \u00a0 Not equal symbol \\verb|\\ne|: $42 \\ne 41$ %two numbers are not equal\n\\end{center}\n\\end{document}\n<\/pre><\/div>\n\n
\n
\"Equal
Not equal commands<\/figcaption><\/figure><\/div>\n\n\n
Going the extra mile, sometimes you may need to write the equal sign but with some add on above or below the parallel lines; to do so you need to load the amssymb package. You can see the generated symbols in the following example,<\/p>\n\n\n
\n\\documentclass{article}\n\\usepackage{amssymb}\n\\begin{document}\n\u00a0 \u00a0 Some variations can be \\\\\n\u00a0 \u00a0 - A dot above: $a \\doteq b$ \\\\\n\u00a0 \u00a0 - A triangle above: $a \\triangleq b$ \\\\\n\u00a0 \u00a0 - A circle above: $a \\circeq b$\n\\end{document}\n<\/pre><\/div>\n\n
\n
\"Equal
Variations for equality<\/figcaption><\/figure><\/div>\n\n\n
Now you have the knowledge to write these useful and super common symbols in your documents with multiple methods and options. In case you wonder whether some variation of this symbol exists, look in the amssymb documentation or on the internet, don\u2019t be shy to ask.<\/p>\n\n\n\n
I hope this post was helpful, by writing you gain more confidence and get more experience, practice makes perfect. Keep writing in LaTeX and until next time.<\/p>\n\n\n\n
