I would, perhaps in a "checking I had it right" - knowing that I was right and they were wrong.

What does BIDMAS stand for?

I don't remember this acronym from my primary school days...

It's the order in which you do multi-stage calculations - Brackets, Indices (powers), Division, Multiplication, Addition, Subtraction.

With BODMAS I believe divide and multiply can be done in any order so although its not what you're used to it's not actually incorrect.

I thought it was B*O*DMAS?

Sorry, that was an awful post. Division and multiplication.

In what way is it wrong?

I have also seen it taught as

Division and multiplication are of equal importance rather than having to be done in a particular order. The same is true of addition and subtraction. You do them in the order you find them rather than have to do division first and then multiplication/addition then subtraction. If the multiplication came first when working left to right then you would do the multiplication before carrying on to the next part of the sum. What was on the wall was therefore not incorrect.

I'm sure we did BOMDAS (Scotland, many years ago)

vodkaanddietirnbru Fri 05-Oct-12 22:42:01

does it really matter as long as they get the operations in the right order and get the right answer?

I was taught

B bless
M my
D dear
A aunt
S sally

.... So M before D...

maybe they've changed it too to match up with the primary school - how do you know how they currently teach it? A lot has changed since I was at school too.

I feel a bit for the teacher with the dodgy Czech translation. I teach a fair few students with very, very little English, and I put quite a lot of stuff through Google translate. I realise it's dodgy, but hopefully less dodgy than my grasp of Lithuanian or Tagalog.

It is nice to sing from the same hymn sheet, but I taught a child who prefered

'depending on what comes first in the sum'

Don't you mean calculation, kim?
