ExpressionsinBar is a simple menubar application which provides powerful computer-aided algebra computations.
It’s a powerful tool for evaluating mathematical expressions that lives in the menubar of your Mac ! So it is always just click away !
It can do numerical calculations – It can also do symbolic math !
Equations can be output in a PDF form that can be pasted into your Documents or Presentations !
It’s the perfect app for teachers, math students, scientists, and the geek among us !
• Unlike most other Equation Editors, ExpressionsinBar helps you resolve the math and then prepares a neat output for an easy insertion in your documents or presentations.
• How to use: Click the Menubar icon and ExpressionsinBar pops open an input expression box. Enter the expression, view the result. With the drag-and-drop feature, results are easily copied into text editors such as Pages or Microsoft Word, or presentation programs such as Keynote or Microsoft PowerPoint. Alternatively export the result of a computation in LaTeX syntax to TeX processors, such as TeXShop or TeXworks.
