When it comes to typesetting equations, LaTeX is often compared to other tools such as Microsoft Word and MathType. While Word and MathType offer more user-friendly interfaces and WYSIWYG editing, LaTeX excels in terms of equation quality, customization options, and compatibility. LaTeX provides finer control over equation formatting and is preferred by professionals in the scientific and academic community.


Method 1: Inline Equations

Inline equations are used when you want to include equations within the text. To create an inline equation in LaTeX, enclose the equation between dollar signs ($). For example: $E=mc^2$.

Method 2: Displayed Equations

Displayed equations are used when you want to present equations as separate blocks. To create a displayed equation in LaTeX, use the equation environment. For example:


Method 3: Mathematical Symbols and Notations

LaTeX provides a wide range of mathematical symbols and notations. To use mathematical symbols in LaTeX, you can either use the corresponding command or include the symbol directly. For example, to represent the square root symbol (√), you can use the command \sqrt or include the symbol directly (√).

Method 4: Equation Numbering and Labeling

To add equation numbering and labeling in LaTeX, you can use the \label and \ref commands. The \label command assigns a label to the equation, and the \ref command is used to refer to the labeled equation. For example, to label an equation as 'eq:energy', you can use the command \label{eq:energy}. To refer to the labeled equation, use the command \ref{eq:energy}.

Method 5: Equation Alignment

LaTeX allows you to align equations using the align environment. This environment provides multiple alignment points for equations. For example:

E &= mc^2 \\
F &= ma
