The third one could be 19. The 1/3 is not necessarily a third of 6 but rather 6 divided by thirds which is 18 + 1 is 19. In fact I would argue it is or it would have been 2 instead of 1/3?........or am I looking too deep?????
No the answer is 1. You can't just work left to right ie 9-3 = 6 then divide by one third (which you correctly say would be 18). Division comes before addition and subtraction.
3 divided by one third is 9, so then its 9 - 9 +1
Think about a caravan engineer charging £50 call out fee plus £20 per hour, for 2 hours the sum is
50 + 2x20
If you work left to right you get 52 x 20 = £1040 rathr than the correct answer of 50 + 40 = £90.

I would think that an American Caravan engineer would invoice as below.
Call out charge ------------$ 50
2 hours @ $ 20 ---------- $ 40
Total. Bill ----------------- . $ 90
Sorry folks but there is no pound sign on this tablet.

Hoping my maths stands up (I'm sure Corners will correct if not)
21, 14, 1 & 81
No.1.
Horse + Horse + Horse = 30, so Horse = 10
10 + (2 Horseshoes) + (2 Horseshoes) = 18, so (2 Horseshoes) = 4
4 – (2 Boots) = 2, so (2 Boots) = 2
Assuming 1 Boot is (2 Boots) / 2 = 1 and 1 Horseshoe is (2 Horseshoes)/2 = 2
Then, 1 + 10 x 2 = (10 x 2) + 1 = 21 [using BODMAS]
No.2.
Apple + Apple + Apple = 30, so Apple = 10
10 + (4 bananas) + (4 bananas) = 18, so (4 bananas) = 4
4 – (2 half coconuts) = 2, so (2 half coconuts) = 2
Assuming 1 half coconut is (2 half coconuts) / 2 = 1 and 1 banana is (4 bananas)/4 = 1
Then, 1 + 10 + 3 = 14
No.3.
Using BODMAS,
9 / (1/3) = 9
9 – 9 = 0
0 + 1 = 1
No. 4.
Red Flower + Red Flower + Red Flower = 60, so Red Flower = 20
20 + (5 Petal Blue Flower) + (5 Petal Blue Flower) = 30, so (5 Petal Blue Flower) = 5
5 - (2 Yellow Flowers) = 3, so (2 Yellow Flowers) = 2
Assuming 1 Yellow Flower is (2 Yellow Flowers) / 2 = 1 and each petal on the blue flower is (5 petals)/5 = 1
Then 1 + 20 x 4 = (20 x 4) + 1 = 81 [using BODMAS]

I now tend to agree

Sorry, its should be 3 / (1/3) = 9 not 9 / (1/3) = 9, I have copied the question incorrectly.
....but the answer is correct to the question (as Corners has already demonstrated).

People dont really realise how important mathematics can be. Important professions like Physics, Engineering, Medical research, Medicine, and IT and many other disciplines need a high level of mathematics knowledge.
Basic maths, as taught in comprehensive schools is allegedly not good enough to prepare students for university studies of those important subjects, therefore as a result, there is a shortage of graduates into those interesting professions.

Top marks to CJ!
By the way, those of us that were taught BODMAS (and this includes me) are showing their age. Its BIDMAS now in schools, the i for indcies.

All that spurious talk about bodmas and bidmas is irrelevant to a student. So unless Parentheses is being used ....which determines what operation is performed first..
The rule of thumb is :- Start at the Left
The rules are straightforward and are as follows :-
- Multiply and divide from left to right.
- Add and subtract from left to right.

Seems odd that I remembered the BODMAS rules (but confess I had forgotten the term) when presented with actual numbers at 3
Yet, when presented with representation just completely forgot to apply them.
Second nature to me as I have had an engineering background throughout my working life.

Corners, I didn't know that, thankyou. Everyday is a School day

How very interesting....
I'll be sure to let my nephew know that his A*s aren't good enough

`Is there any significance in the fact that the UK has dropped to 27th place for maths in the civilised world. I'm sure someone more knowlegable than me will elucidate. Should we be worried ???
This thread is about Standards of basic maths after all.

A few years ago I worked fairly closely with the ICI technician apprenticeship scheme. The people on the scheme were high achievers but ICI sent them all back to college as the maths they left school/college with just wasn't suitable for industry. So IMO
something not right if the curriculum doesn't teach what industries/vocations required0 -
Basic Maths K! (....well statistics)
That is just a page of place names and numbers, so unless you are stating how the numbers have been derrived, it means nothing!
Measures, sample size, spread etc. etc.

In these eco-sensitive times I would have expected BIOMAS

Ian, is it not the curriculum that is at fault?. Surely the Teachers are just sticking to a set of Govt rules. That is then checked rigorously by ofsted to ensure they are sticking to the curriculum.

Write your comments here...You need to know the rules of maths. It isn't logical. 'You can't just work from Left to Right ' So, when I sort the rules out I'll be able to do it!! Till then all i need to know is that my engineer hasn't over charged me!!

With the current focus on STEM (Science Technology Engineering Maths), which is a good thing, (I'm a STEM Ambassador) I argue the M should be changed to Manufacture as the first three are underpinned by maths and the output should be to make (manufacture)
tangible things in the three fields.The recent drive to get more graduates as purely a tick box exercise is not delivering the levels of learning for Engineering. Engineering Technicians are probably the more benefit to society. There are 3 legally protected levels of Professional Registration
that youngsters would be best encouraged to aspire to, Eng Tech, IEng and CEng, all of which are achievable without a degree. To focus young minds purely on the academic graduate route is not sufficiently productive for society, hence the oft laudered skills
gap that is whinged about.It makes me question if there is a skills gap, I believe it's an experience gap, then who is making the determination on requisite skills if not competent people currently holding those skills. If the unknowing are making those decisions it's a bit like
the blind leading the blind.This arena is fundamental to human existence. Humans need clothes on their backs, food in their belly and roof over their head; all of which are delivered by STE. The rest are luxuries.
Bit deep, but something that I'm passionate about
