I think this had been fully examined, thanks guys, I shall prepare more newbie questions to check your knowledge of course. =p Just jiving at the UK thing, I've heard people here call it BODMAS too.

$ \frac{1 \ + \ 1 \ + \ 1 \ + \ 5 }{1 + (2) + 1 + 2} = \frac{1}{1} + \frac{1}{2} + \frac{1}{1} + \frac{5}{2} $ You can replace $5$ by any number you wish and it still holds true. LOL there are an infinite number of cases where it works ... but that is not enough. Thought you might find this interesting

"PEDMAS" can be remembered by the mnemonic "Please Excuse My Dear Aunt Sally". Is there a mnemonic for "BODMAS"?

Also worth mentioning is that multiplication and division must be done in the order that they occur from left to right. For example if you encounter 12÷3x2 the correct answer is 8

When I was a math teacher, I provided the following order of operations: 1. Parentheses 2. Exponents 3. Multiplication/division 4. Addition/subtraction 5. Line division Notes: 1. Multiplication and division are equal in order. So is addition and subtraction. Whichever comes first, you do first. 2. "Line division" refers to a line drawn between the elements of an expression (as in the the second post).

Would it still cause confusion if examples were given? If so, please give an example of a possible confusion. Last edited by Timios; July 9th, 2017 at 11:50 AM.
