[20] [21] The acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication/Division, Addition/Subtraction, [22] is common in the United States [23] and France. [24] Sometimes the letters are expanded into words of a mnemonic sentence such as "Please Excuse My Dear Aunt Sally". [ 25 ]
Ah, well. It takes a long time to do a carefully rewrite, and only seconds to revert it.

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).
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
The syntax of mathematical expressions can be described somewhat informally as follows: the allowed operators must have the correct number of inputs in the correct places (usually written with infix notation), the sub-expressions that make up these inputs must be well-formed themselves, have a clear order of operations, etc. Strings of symbols ...
An example of mnemonic devices are PEMDAS or Please Excuse My Dear Aunt Sally; this is a device for arithmetic when solving equations that have parenthesis, exponents, multiplication, division, addition, or subtraction and what order to do each calculation. Words or an acronym can stand for a process that individuals need to recall.
