The Calctex plugin enhances Obsidian by automatically solving LaTeX formulas and displaying the results inline. Users can append an equals sign (`=`) to their formulas to trigger the calculation, with solutions shown directly in the editor. For convenience, the solution can be added to the document by clicking it or pressing the `Tab` key. This plugin is designed to simplify mathematical workflows, making it an ideal tool for users working with equations and calculations in their notes.

The Mathpad plugin enhances your Obsidian experience by integrating a powerful calculator and plotting system. Based on Nerdamer for symbolic and numeric calculations, and function-plot for 2D plotting, Mathpad offers a sidebar, code block, and inline block features. The sidebar functions as a stand-alone calculator, capable of providing dynamic code blocks or static LaTeX results that can be inserted into your notes. It also allows the inclusion of computations and plots directly within notes through code blocks and inline code.

The Meld Calc plugin enables users to evaluate mathematical expressions directly within their Obsidian notes using the fcal library. It supports basic arithmetic, percentages, and advanced calculations with precision. Users can write expressions, select them, and evaluate them via the command palette to either insert the result into the note or copy it to the clipboard. The plugin also supports variables and multiline expressions, making it ideal for handling more complex calculations. It includes built-in units, functions, and constants to enhance its flexibility for a variety of use cases.
