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's the perfect app for teachers, math students, scientists, and the geek among us!

A GORGEOUS OUTPUT
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. Mathematical expressions are presented in high-resolution PDF form that can be pasted into your Documents or Presentations!

A VERY SIMPLE USER INTERFACE

• Click the Menubar icon and ExpressionsinBar pops open an input expression box. Enter the expression, view the result.
• Beautiful output easily copied into text editors such as Apple Pages or Microsoft Word, or presentation programs such as Apple Keynote or Microsoft PowerPoint.
• Alternatively export the result of a computation in LaTeX syntax to TeX processors, such as TeXShop or TeXworks.
• Scrolling panels with easy to use functions
• Menu with variables, functions, syntax and tips
• Use keyboard arrows to navigate function arguments
• Easily select to render "input only", "input =", "result" and "input and result"

KEY MATHEMATICAL FEATURES:

• Constants (π, e, etc.)
• Integers, fractions, floating numbers
