[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 ]
In mathematics, exponentiation, denoted b n, is an operation involving two numbers: the base, b, and the exponent or power, n. [1] When n is a positive integer, exponentiation corresponds to repeated multiplication of the base: that is, b n is the product of multiplying n bases: [1] = ⏟.
In certain regions, PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition and Subtraction) is the synonym of BODMAS. It explains the order of operations to solve an expression. Some mathematical puzzles require top to bottom convention to avoid the ambiguity in the order of operations.
Of course the article has to mention parentheses, and does. My point is that parentheses are a symbol of grouping, not an operation, and that PEDMAS is a mnemonic, not a rule of mathematics. Rick Norwood 09:52, 13 April 2023 (UTC) Agree that the definition subsection is not the proper place to introduce the PEMDAS mnemonic.
PEMDAS Please - Parenthesis Excuse - Exponents My - Multiplication Dear - Division Aunt - Addition Sally - Subtraction In the UK, the phrase BIDMAS is used instead; Brackets, Indices, Division, Multiplication, Addition, Subtraction. [35] BEDMAS is more commonly used in Canada and New Zealand. [36]
The radical symbol (√) for square root was introduced by Christoph Rudolff in the 1500s, and parentheses for precedence by Niccolò Tartaglia in 1556. François Viète’s New Algebra (1591) formalized modern symbolic manipulation. The multiplication sign (×) was first used by William Oughtred and the division sign (÷) by Johann Rahn.

The next order of operation (according to the rules) is exponents. Start at the left most value, that is, 4, and scan your eyes to the right and search for the first exponent you come across. The first (and only) expression we come across that is expressed with an exponent is 2 2. We find the value of 2 2, which is 4. What we have left is the ...
