PlainCalc is a buttonless, algebraic-entry, mathematical calculator with variables. To use PlainCalc, type an expression or assignment and press Return or Enter. Unlike most calculators I've seen, PlainCalc allows you to indicate multiplication by juxtaposition, e.g., you can write 2?r instead of 2*?*r.
What's New
Version 2.3:
- The size and position of the window is now stored with documents.
- There is a Preferences dialog where you can set text colors and a timeout.
- The % sign is a built-in constant whose value is 0.01, so that for instance you can write 73% instead of 0.73.
- Improper recursive functions will no longer freeze or crash PlainCalc; instead, you will get a message saying "Timed Out" or "Calculation Crashed".
- If your language preferences specify that the decimal separator is a comma rather than a period, then PlainCalc expects you to enter decimals using the comma, and reports results that way. In this case, you must separate the parameters of a multi-parameter function using semicolons rather than commas.

And the developer is very responsive: within days of my suggesting it, he added the ability to define default font and size, and pointed out that commenting elements of a calculation was possible simply by using option-return to add a line-break without evaluating the preceding text.
Arguably it is a disadvantage that user-defined constants and functions cannot be saved globally, but since PlainCalc can (very usefully) save calculations as documents, anything worth saving in a specific field can be stored in a document.
If all you want is to evaluate 45.226/9.4, then there are even simpler ways to do this, and if you are looking for more exotic functions, then you might want to look at SpeedCrunch or pay for an advanced scientific calculator, but for doing complex but relatively straightforward maths, PlainCalc hits the sweet spot for me, especially now that the venerable MathPad is beginning to grow whiskers.
