As seen in the example above, LFE expressions are written as lists, using prefix notation.
2.
It is common to regard formulas in infix notation as abbreviations for the corresponding formulas in prefix notation.
3.
This makes it possible to design special infix and prefix notations, for example in mathematics and physics applications.
4.
The shunting yard algorithm can also be applied to produce prefix notation ( also known as Polish notation ).
5.
An example shows the ease with which a complex statement in prefix notation can be deciphered through order of operations:
6.
In some fields, it is common to use infix notation for binary relations and functions, instead of the prefix notation defined above.
7.
To evaluate order of operations under prefix notation, one does not even need to memorize an operational hierarchy, as with infix notation.
8.
Once analyzed, a statement in prefix notation becomes less intimidating to the human mind as it allows some separation from convention with added convenience.
9.
Prefix notation is especially popular with stack-based operations due to its innate ability to easily distinguish order of operations without the need for parentheses.
10.
This is the general theory behind using stacks in programming languages to evaluate a statement in prefix notation, although there are various algorithms that manipulate the process.
