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

How do you use the word mnemonic in a sentence?
mnemonic wha....?
What are the formulas for basic algebra?
If you are asking 'in what order are arithmetic operations performed'; One useful mnemonic is BEDMAS. This order is Brackets, Exponents, Division, Multiplication, Addition, and Subtraction. Sometimes called Order of Operations.
What is the full meaning of BODMAS?
As a mnemonic for order of operations in algebra, it's: Brackets, Operations (exponents, square routes, etc), Division bars, Multiplication, Addition, Subtraction.
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
How do you remember the months in order?
I am not aware of any mnemonic. It is simplest just to memorise the order.
What is a mnemonic cartoon?
A mnemonic device is something that helps a person remember something. For example, sentences made up to remember the order of Mitosis. A mnemonic cartoon is similar, except it is a drawing to help a person remember.
How can order of operations be changed?
If you put in parentheses, you can change the order of operations in many cases, as parentheses come before everything in the order of operations.
What does mean if a calculator follows the order of operations?
It means that the calculator can follow the order of operations and do the order of operations for you but, you need to know how to do them on your own too.
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.
What is P E M D A S?
PEMDAS is an mnemonic for the order of operations, please excuse my dear aunt Sally. This is what it stands for: P Parenthesis E Exponents M & D Multiplication and Division, perform operations from right to left A & S Addition and Subtraction, perform like M & D Hope this helps!
