Description
ExpressionsinBar is a simple menubar application which provides powerful computeraided 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 draganddrop 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.
• Key features:
 Constants (π, e, etc.)
 Integers, fractions, floating numbers
 Sequences, lists, vectors, matrices, strings
 Operators (+, , *, /, ^)
 Arithmetics on integers, rational, and floating numbers
 Arbitrary precision arithmetic, operating on signed integers, rational numbers, and floating point numbers
 Operations on fractions (integer and fractional parts, numerator, denominator, simplification, continued fraction expansion of real)
 Real functions (max, min, round, floor, sign, frac, ceil)
 Complex functions (re, im, abs, conj, arg, affix)
 Polynomials

 Access to several fundamental constants of nature
• Extended user interface and keyboard features
 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"
• Render using LaTeX syntax for fastest typesetting
 "@" feature to interpret input with LaTeX syntax
 Flexible and easy way to format equations
 Use it to write chemical reactions (such as @NaOH+HCl \rightarrow NaCl+H_2O)
• A simple User Interface
 Display short "howto" when typing
 Automatic completion of functions when typing
 Zoom slider
• Services integration  access the powerful tools within other applications, such as Word or Textedit
 Replace Selection by Result
 Replace Selection by Result in LaTeX format
 Replace Selection by Image of Result
• Support for OS X 10.8 and beyond

Ratings and Reviews
This program is a must buy
For the first version, 0.62:
I saw the description of this program and thought: What the heck, for $2.99 I will take a chance. Well, instead of being dissapointed I am very happy, as this program does all it claims it will. If you routinely need a CAS calculator and editor, this is the program for you.
For the second version, 1.0:
I never thought this program could be improved upon but the author of it pulled it off. If it were possible, I would give it more than 5 stars. With the addition of the virtual keyboard, this program became even easier to use. Normally, if I wanted a quick CAS answer I had to fire up Mathematica or Maple. I am sure that everyone probably knows the power of these two programs. Unfortunately, if you want to do something simple, the use of the aforementioned programs was like using a sludge hammer on a thumb tack; plus, you had to wait while it loaded. Yes, for easy and quick CAS solutions, this program offers instant gratification.
For the curious, it is my understanding that the CAS engine in this program is GIAC, which is used in the HP Prime calculator. GIAC has been available for many years and is a very competent CAS program. In any event, the author of this program did a nice job of making a very user friendly interface.
Lastly, I noticed the price of this program increased to $3.99, which is still the bargain of the year.
nice tool
Useful for singleline computations. 4 stars for good tool plus 1 extra star for “InBar” convenience.
For multistep work where storing intermediate expressions and producing plots is useful, I recommend the CAS View within GeoGebra (free for computers and tablets). [Both ExpressionsInBar and GeoGebra base their ComputerAlgebraSystem (CAS) on Giac/Xcas.] MathMinion documents have an interesting structure; it is free for Mac and iOS. For heavyduty work with free tools, I suggest SageMath, Maxima (part of Sage), Axiom, Reduce; also see Wikipedia for several articles and comparison tables about CAS.
ExpressionsinBar
If you would like to write mathematics in text based programs (like Pages), you will love this. While the previous reviewer is correct in that it did not work, I contacted the developer who fixed the problem in a few days. So my experience with this is about 23 days. It's maybe not perfect but for $2 it's a steal. Your next choice is about $100. If you like math buy it and try it. PS you need to read the tutorials page on their website (click on the actions menu).
