BODMAS = Brackets, Of, Divide, Multiply, [Add and Subtract]

BODMAS = Brackets, Order, Divide, Multiply, [Add and Subtract]

BODMAS = Brackets, Other, Divide, Multiply, [Add and Subtract]

BIDMAS = Brackets, Index, Divide, Multiply, [Add and Subtract]

I have bracketed Add and Subtract as when they are found together, they are done in the order they are found: from left to right.

eg 1 + 2 - 3 is (1 + 2) - 3 and NOT 1 + (2 - 3) as the mnemonic would suggest.

With Divide and Multiply, they can be done either left to right, or by doing the divide first, and the correct answer will be found, eg:

2 x 6 ÷ 3 = (2 x 6) ÷ 3 = 2 x (6 ÷ 3)

Note:

6 ÷ 3 x 2 = (6 ÷ 3) x 2 ≠ 6 ÷ (3 x 2)

But the last possibility would not be attempted as 'left to right' and 'divide first' are the same calculation (doing the division); showing that following strict 'DM' of BODMAS always works.

My own creation: to get the sum correct, you will be under the watchful eye of the Bod Tsar:

BODTSAR = Brackets, Of/Order/Other, Divide, Times, Subtract, Add (in order to get the) Result.

Which fixes the slight imperfection that the B*DMAS don't show that the pairs of operations Divide & Multiply, and Subtract & Add have the same priority and are done in left to right order. However, if you always Divide before Multiplying (Timesing) and Subtract before Adding in those pairs, you will get the correct result, hence my mnemonic

What are the Order of operations for evaluating expressions?

Please Excuse My Dear Aunt Sally is an often used mnemonic for remember the order of operations.Some people use the acronym PEMDAS.Either way, the order of operations isParentheses, Exponentiation, Multiplication/Division, Addition/Subtraction


How did the PEMDAS start in math?

Please Excuse My Dear Aunt Sally. Please Execute My Dumb Assassin Sam Please Excuse My Deadly Angry Samurai Panda Express Makes Delicious Avocado Soup PEMDAS, Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction, is a mnemonic for the order of operations in any mathematical expression, not just those in algebra. Perhaps "Wright or Wrong: Teaching the Order of Operations" (Schrock & Morrow, 1993) is the earliest publication of the mnemonic. The standard order of operations has been around a very long time, of course. I seem to vaguely remember this mnemonic from the 70s or 80s, but it was presented as a flawed, misleading device (e.g multiplication is really same order of precedence as division, and addition is same order of precedence as subtraction), so I never relied on it. I'm not confident in that recollection, anyway


Do you muliply then subtract?

Yes. The standard order of operations is Parenthesis or Brackets, then Exponents and Roots, then Multiplication and Division, then Addition and Subtraction. We were always taught the mnemonic: Please Excuse My Dear Aunt Sally

When was bedmas first used?

BEDMAS, an acronym for Brackets, Exponents, Division and Multiplication, Addition and Subtraction, is a mnemonic used to remember the order of operations in mathematics. While the specific term "BEDMAS" appeared in the 20th century, the concept of the order of operations has been used in mathematics for centuries, evolving from earlier notations and practices. The formalization of these rules has been attributed to various mathematicians and educators over time.


What is meant by aide memorie?

Is this perhaps something someone uses to help him remember something? For example, in mathematics, school children learn about the order of operations. In order not to forget what is to be done first, they learn the mnemonic 'please excuse my dear aunt sally'. This means do the following in this order: parenthesis, exponents, multiplication, division, addition then subtraction.
