		RPN is an interface program which lets you operate a TI89 or TI92+ calculator using an RPN interface, instead of the normal algebraic interface.
		RPN is a stack-based interface, which is often faster to use than algebraic entry, especially for complicated expressions.
		RPN is an acronym for reverse Polish notation, which describes the method used to enter operators and operands.

	RPN
		RPN allowed HP to produce a pocket calculator that could evaluate arbitrary expressions using the available technology.
		Once the technology to produce algebraic compilers could fit into a pocket calculator, most RPN users had decided that RPN was more efficient and consistent for the user as well as for the calculator.
		The beauty of RPN is that this model extends to arbitrarily complex expressions without parentheses and precedence rules.

	RPN or DAL?
		RPN required only 9 keystrokes instead of the 11 required by a standard calculator.
		The RPN method, however, proved to be successful not only from the point of view of chip design efficiency but also from the point of view of human operation.
		More over, non-HP scientific calculators, such as the ones manufactured by Texas Instruments, relied on the algebraic model for their data-entry by providing parentheses as part of the keyboard, at the beginning that imposed limitations on the number of nested levels that could be handled, but these limitations started to disappear as new models arrived.

	RPN Tutorial
		RPN, HP's logic system, was named in honor of a logic notation devised by the Polish mathematician Jan Lukasiewicz.
		Originally developed to make the evaluation of algebraic expressions as simple as possible, RPN has been implemented in HP calculators be means of the stack and postfix operators.
		RPN enables you to see all intermediate answers, to recover easily from errors, to reuse numbers without reentering them, to solve problems one step at a time, and to evaluate virtually any expression without copying and remembering parentheses.

	RPN - Reverse Polish Notation (Site not responding. Last check: 2007-10-13)
		Engineers at the Hewlett-Packard company realised that RPN could be used to simplify the electronics of their calculators at the expense of a little learning by the user.
		On most RPN calculators this is called the "Enter" key and fulfills a similar function to an equals key on a conventional calculator but in reverse.
		Although RPN seems strange to the uninitiated, people who overcome the initial hurdle find it a powerful and elegant tool which is ultimately easier to use.

	HP 15C RPN How To
		RPN was developed in 1920 by the Polish mathematician Jan Lukasiewicz as a way to write a mathematical expression without using parentheses.
		RPN allows the calculator to solve very complex equations with out the need for lots of temporary storage, or complex programing.
		RPN entry calculators mimic the way calculations are done on paper, which makes it more natural when doing calculations..

		RPN (Reverse Polish Notation) provides a way to order boolean operations in such a way as to avoid the need for parenthesis.
		RPN uses the concept of a stack for applying operators to operands.
		Evaluation of the RPN notation results in a single result set such that the number of operators is always one less than the number of field/value pairs.

	Examining Risk Priority Numbers in FMEA
		When using this risk assessment technique, it is important to remember that RPN ratings are relative to a particular analysis (performed with a common set of rating scales and an analysis team that strives to make consistent rating assignments for all issues identified within the analysis).
		Therefore, an RPN in one analysis is comparable to other RPNs in the same analysis but it may not be comparable to RPNs in another analysis.
		This may not be high enough to trigger corrective action based on RPN but the analysis team may decide to initiate a corrective action anyway because of the very high severity of the potential effect of the failure.

	RPN, An Introduction To Reverse Polish Notation
		RPN is logical because the user first gives the number and then tells what to do with it.
		RPN keeps a record of calculations by placing them in a stack(2).
		Stack: A stack, also called LIFO (last-in, first-out), is the basis of the RPN system as it is the 'memory' that allows the user to enter numbers.

	Reverse Polish notation - Wikipedia, the free encyclopedia
		Reverse Polish notation (RPN), also known as postfix notation, was invented by Australian philosopher and computer scientist Charles Hamblin in the mid-1950s, to enable zero-address memory stores.
		Implementations of RPN are stack-based; that is, operands are popped from a stack, and calculation results are pushed back onto it.
		Friden introduced RPN to the desktop calculator market with the EC-130 in June of 1963.

	RPN Calculator Entry Mode : Educalc.net
		RPN or Reverse Polish Notation is an efficient data entry method that eliminates the need to enter parentheses in equations, has been a favorite of HP calculator fans for more than 30 years, and it remains alive and well at HP.
		In the 1920's, Jan Lukasiewicz developed a formal logic system which allowed mathematical expressions to be specified without parentheses by placing the operators before (prefix notation) or after (postfix notation) the operands.
		HP produces certain models of calculators with RPN because it is an extremely powerful yet simple way to perform computation.

	RPN Calculator User Manual
		The simplest way to learn to use the RPN interpreter is to see several examples side by side with the equivalent calculation done using the Python interpreter.
		Since the stack is such a central data structure to the RPN interpreter, it is necessary to have an easy way to move data on and off the stack from the Python interpreter.
		An interesting extension to the RPN calculator is to add polynomials in a manner that allows them to be manipulated like numbers.

	HP calculators / RPN, An Introduction to Reverse Polish Notation
		Hewlett-Packard Co., realizing that Lukasiewicz's method was superior to standard algebraic(1) expressions when using calculators and computers, adapted RPN for its first hand-held scientific calculator, the HP35, in 1972.
		For example, to perform addition, you need to enter 2+4 (algebraic), but to perform a sine calculation, you need first to enter the number and then to press the SIN button, which is a RPN method of entering the equation.
		Believe it or not, the process of using RPN is similar to the way you learned math.

	[Tutor] Simple RPN calculator
		Now, with a RPN calculator, you input your expression as a tree, where the leaves are the operands and the nodes are the operators, in the order where they have to be processed.
		Most RPN calculators also include an algebraic mode to allow you to see the difference; in the case of the HP48 series, using said algebraic mode immediately makes you feel the calculator's main weakness: its processor is ridiculously slow (4 MHz 4-bit Saturn CPU).
		Although as far as pocket calculators are concerned, you don't have a choice anymore -- HP stopped producing calculators a few years ago, having basically done nothing in 15 years to improve the design of the 48/49 series.

		RPN stands for "Reverse Polish Notation," a parenthesis-free method for performing calculations.
		In order to solve this problem on an algebraic calculator, you must carefully place parentheses between the operations (assuming your calculator has parentheses).
		Once you begin to get a feel for RPN, you will realize it is the easiest way to solve all but the simplest problems.

	Non-HP RPN Calculators
		This is a list of calculators from the late 1960s and 1970s which used Reverse Polish Notation (RPN) for their calculation.
		I believe they function identically to the rpn style, except they have no enter key and only what we would call a two-level "stack".
		This style predates RPN by several hundred years and it's really stretching to call the two number registers a "two-level stack" because these machines supply no stack operations whatsoever.

	An RPN calculator in a prompt for the X2 editor
		A feature of RPN compared to older HP calculators is that the (a) all of the stack is visible in the prompt window, and (b) there is no limit to the depth of the stack (unless you want to set one).
		This is the way that most RPN calculators show the stack too, although they have the confusing habit of calling the bottom number the top of the stack.
		RPN can also do unit conversions in a flexible way that is easy to customize and to control.

	The Evolution of RPN & Numeric Entry
		RPN is formally traced to prefix and postfix mathematical systems proposed by Jan Lukasiewicz in 1951.
		There were no arrow symbols etc. Friden never mentioned "Polish", "reverse Polish" or "RPN" in its calculator documentation and only briefly mentioned that the calculator used a "stacking principle".
		Since HP first applied the acronym "RPN" to its calculators, and because most users mean HP's specific implementations when they refer to "RPN", the museum doesn't classify the Friden ECs as true RPN calculators.

		So in effect an RPN calculator is offloading this work to the calculator user, resulting in simpler logic design in the calculator.
		Nowadays the design issues of using conventional bracket notation in an electronic calculator are trivial, and yet users of RPN calculators rarely seem to want to move over to the more conventional algebraic logic.
