In ireland we have BOMBdas

Brackets
Of (division)
Multiplication
Division
Addition
Subtraction

PS Brackets would make it more clear

I was taught BODMAS in school and that was 20 years ago or so.

Apparently, multiplication and division are of equal precedence which I never knew until now.

We couldn't afford acronyms when I were a lad
No wonder I was so crap at maths

**Swordwind**

Yeah, it doesn't really matter which order you do multiplication or division in, it still works. Many grueling years of additional maths taught me that.

Also, it's 5.

**Paul**

It's 5 and anyone who tells you otherwise should be burnt as a heratic.

But then so should anyone who fails to use brackets except to make a point about thw dangers of not using them.

So should every teacher who talks about an angle measurer rather than a protractor, or still teaches i before e.

Don't even get me started on the wrongness of GCSE chemistry. The lies to children they tell.

**Swordwind**

I have just learnt that everything I learnt in IGCSE chem is a lie.

It hurt so much.

**Paul**

It gets worse. I started my degree and one of the first things the semiconductors lectures said was "you know how when they told you at alevel that everything you were told at gcse was a good model but wrong? Well it's the same now, but even this is wrong but it works for now"

Finding out the concept of electrons flying round a nuclius at set levels, or even at all, is most disconcerting.

**Swordwind**

And here I was thinking knowing 1s2 2s2 2p6 made me smart.

**Melissia**

Five.

Multiply first, then add/subtract. Duh?

I didn't get any fancy acronyms either, just had to remember the order without it.

**Orlanth**

5

Because the party says so.

**Lord Scythican**

Did anyone else get 7?

Seriously though, if someone is teaching this left to right and they are a teacher, they need to be fired.

Because if it left to right, then you can take the same operations and reverse them giving two different answers.

1+2*2=?

2*2+1=?

The whole PEMDAS is there to make sure that doesn't happen. Of course from the looks of it, this is pretty much known in this thread. Where the hell are they teaching this wrong anyway?

**CiaranAnnrach**

I honestly doubt this is the new "norm" for teaching. My mother is a middle school math teacher, and if this was a change made to the curriculum I'd have heard her complain about it by now.

What she has complained about before is nowadays her kids can't seem to do simple math without a calculator. Like multiplying simple fractions. There's definitely an increase in the amount of spoon-feeding that's going on with today's generation compared to when I was in school, or when my parents were.

**lord commissar klimino**

12 people disgust me!

seriously though, i hate math,and suck at it,and even i know this. are 12 people just idiots,or are there really teachers out the who teach something so important wrong?

**Blacksails**

The people who answered 6 make me sad...

I learned BEDMAS (Brackets, exponents, division/mulitplication, addition/subtraction).

Regardless of maths formula *moving on* essentially, its that this works. I have always been taught, even in my advanced maths classes, that formula is done this way. Devision, Multiplication, then subtractions and finally additions. However, brackets also make a difference, but not in this!

PEMDAS

Parentheses, Brackets(if involved), Exponent, Multiplication, Division, Addition, Subtraction. Not Division and then multiplication.

Its usually remembered as "Please Excuse My Dear Aunt Sally" or "Please, Bob, Excuse My Dear Aunt Sally".

Divison and Multiplication are of equal precedence IIRC, so the order doesn't really matter.

No, the order matters, the order always matters! Its not PEMorDAorS or PEDMSA, its PEMDAS!

I've never heard of 9 year olds taking Algebra, in the US.

**Melissia**

Yeah, it's a sad state of affairs.

**Ratius**

Was the answer 5?
I've had quite a few to drink

**Melissia**

If you had two beers, then doubled the amount of beers you had, then had one more beer, how many beers have you had?

Hahahahah Mel.

Ok Im close, but what if one or two cheeky Greygoose infiltrated for 1-2 more rounds

I'll see your PEMDAS and raise you both a BODMAS and a BIDMAS.
