When the user is unsure how a calculator will interpret an expression, parentheses can be used to remove the ambiguity. [ 3 ] Order of operations arose due to the adaptation of infix notation in standard mathematical notation , which can be notationally ambiguous without such conventions, as opposed to postfix notation or prefix notation ...
In computer science, an operator-precedence parser is a bottom-up parser that interprets an operator-precedence grammar.For example, most calculators use operator-precedence parsers to convert from the human-readable infix notation relying on order of operations to a format that is optimized for evaluation such as Reverse Polish notation (RPN).

Video: Keys pressed for calculating eight times six on a HP-32SII (employing RPN) from 1991. Reverse Polish notation (RPN), also known as reverse Łukasiewicz notation, Polish postfix notation or simply postfix notation, is a mathematical notation in which operators follow their operands, in contrast to prefix or Polish notation (PN), in which operators precede their operands.
1) PEMDAS is a mnemonic, not a "rule" so it's premature to introduce it in the definition section 2) Operator order is applied both inside and outside the parentheses 3) Parentheses are applied recursively inside to outside if more than one set. I prefer to resolve this via reaching consensus here on the talk page rather than edit warring ...
It is not known whether there is an integer for which n π is an integer, because we could not calculate precisely enough the numbers of digits after the decimal points of . [ 22 ] [ additional citation(s) needed ] It is similar for n e for n ≥ 5 {\displaystyle n\geq 5} , as we are not aware of any other methods besides some direct computation.
[18] [19] He used the method of exhaustion to calculate the area under the arc of a parabola with the summation of an infinite series, and gave a remarkably accurate approximation of pi. [20] He also defined the spiral bearing his name, formulae for the volumes of surfaces of revolution, and an ingenious system for expressing very large numbers.
Piphilology comprises the creation and use of mnemonic techniques to remember many digits of the mathematical constant π.The word is a play on the word "pi" itself and of the linguistic field of philology.
