What he said ^^
I don't personally care if someone cannot do maths correctly (unless it affects me personally like giving me the correct change etc
) but you can't go saying "FACT" and expect people just to accept it when it is clearly wrong.So if you use a calculator that does not follow the correct rules for mathematics then the answer is ok "coz it says so on the screen" ?
nope just means you wasted your money
No, sorry, you are just wrong.
In the absence of brackets, you do not just go from left to right, you apply the rules according to order of operations.
Brackets
Orders
Division
Multiplication
Addition
Subtraction
So as there are no brackets, no orders and no division, the first operator you use is the multiplication (40x0), then the addition.
This isn't negotiable, this isn't opinion, these are the hard and fast rules of mathematics. If you don't do it, you're doing it wrong and you don't understand maths. I know this country has massive issues with poor education, literacy and numeracy, but this sort of thing does actually scare me...
I'll do some real maths when you can write "real" English
p.s. this is a tongue-in-cheek comment
I know
It's a mathematical fallacy (like 0 = 1) that I couldn't be arsed to explain but you busted me
As for my English I apologise I type faster than I think sometimes, like most people on here. (also see my sig!)

I can't believe this thread is still going. It's like the plane on the treadmill incident all over again...

I’ve never seen so many mathematicians in one place before.
It's not even real maths this is proper basic stuff. It's less excusable than my bad grammar! Sure we all forget things but the acronyms like BODMAS never leave you surely!
other ones I can still remember which I imagine many others will know what they are instantly.

So why not put the bloody brackets in then? No-one really cares (apart from 'ooooh, I'm so clever because I did ADVANCED maths and I'm therefore much better than you' clippies).
These so called ''''rules'''' were not taught at GCSE levels 20 years ago. That is a fact, so poke that where the sun don't shine pal
.Oh god no!
But it wouldn't fly...

Of course it would, it will 'fly' at any point when lift is greater than mass. Lift is generated by the movement of air over the wings, facilitated by the propeller.
This isn't advanced maths... Order of operations is covered at Key Stage 3 (11-14)

As for why not put the brackets in, there's no need, you are not altering the default order of operations so you don't need them to get the correct result. The only reason to put them in is to deal with people who don't understand maths.

They'd have been taught before GCSE, that's the point.

They were taught to me at the age of 12 or 13 which was 14/15 years ago.
