Why do they find basic maths so unachievable??

It's shocking and I am appalled by the lack of any basic maths skills in the women candidates.
The one in the board room actually saying without any embaraassment that she was not good at figures but a least she gave it a very bad attempt.
If these women represent some of the most promising business hopefuls this country has to offer, well frankly I am at a loss as to how to adequately express my dismay.
Working out margins and unit prices involves nothing more than simple addition, subtractions and multiplication, all with the aid of a calculator.
From the way they were going on you would have thought they had been asked to differentiate something or similar. :mad:
None of them deserve to win for this very reason IMO

Poor numeracy blights the economy and ruins lives.
Universities dumbing down on maths to fill places.
And it goes on and on.
In another thread in another forum here I asked whether people could calculate
3 + 7 x 4
Many couldn't. But I was roundly attacked for pointing out that people didn't understand maths at this level and giving them links where they could improve their maths.
It's a major social problem, and now that poor maths is ingrained in the adult population, even if school education was improved now it is still going to be causing us major problems for a very, very, long time.
3 + 7 x 4"
Unfortunately maths isn't as simple as you think and full of wacky contradictions.
3 plus 7 is 10. 10 x 4 is 40.
But it's not. According to Google the answer is 31
https://www.google.com/webhp?complete=0&hl=en#hl=en&complete=0&site=webhp&q=+3+%2B+7+x+4+&oq=+3+%2B+7+x+4+&aq=f&aqi=&aql=&gs_l=serp.12...0l0l2l228958l0l0l0l0l0l0l0l0ll0l0.efis.&bav=on.2,or.r_gc.r_pw.r_cp.,cf.osb&fp=f7870fcbd47f4a8c&biw=1100&bih=510
3 + (7 x 4) the answer 31. 7 x 4 being 28 plus the 3 to make 31.
So there you go. My calculator and my brain make it 40, Google makes it 31.
The correct answer is 40. Well it was the last time I added 3 to 7 and then multiplied by 4.
I hope you are only pretending to disagree with Goggle ( and the rest of the educated world)
What is 3 + 7 x 4?
I make it 40.
What do you make it?
Type in
3 + 7 x 4
in Google and see what number they give. It's 31, not 40.
Also, I'm no maths expert but a number, say, 4 multiplied by zero can never be zero. It's impossible and yet we're taught that it is zero. This is a nonsense. Once you establish a number in a maths equation you can't pretend it doesn't exist.
BODMAS floopy, BODMAS (31 is correct BTW);)
The correct way to do the calculation is to imagine it as two separate calculations:
3 + 7 x 4 = 3 + (7 x 4)
= 3 + 28
= 31
Have you ever heard oh BODMAS? The correct answer is 31.
Bodmas is Brackets Other/Over Devision, Multiplication, Addition, Subtraction. So whatever order the calculation is in, you calculate by doing the method of which initials is the closest to the front of the word BODMAS.
7-2+6(3-2)
Bracketsodmas
7-2+6
BodmAdditions
7-8
BodmaSubtraction
Answer is minus 1.
No, it's not. With respect, it's 40.
Three (hello 3!) plus seven (hi you sexy 7!) make 10. I think we all agree on that. Okay, so you got your nice 10. 10 x 4 is 40. The answer is 40 because Winterfire asked:
3 + 7 x 4.
He/she didn't ask:
3 + (7 x 4)
Hi Floopy
The rule of BODMAS gives the order in which the different functions should be calculated.
Brackets
Of
Division
Multiplication
Addition
Subtraction.
As the formula above uses multiplication and addition you first multiply 7 and 4 (=28) and then add the 3, et voila, 31
Pretty sure you're just a WUM now.
You are wrong. Winterfire didn't put any brackets into his maths question therefore the answer is 40, not 31. I know this for a fact because I checked on my calculator. 3 plus 7 times 10 on my calculator is 40. FACT.
Google is wrong, you are wrong.
Well then you don't have a scientific calculator and you need to get an up to date one.
3 + 7 x 4.
BODMAS
M=Multiplication
A=Addition
And for that matter:
B=Brackets
O=Other (Square root signs etc.)
D=Division
S=Subtraction
M is higher in the order then A, so therefore, no matter the written order of the calculation, you do the Multiplication first.
So...
3 + 7 x 4
3 + 28
Answer is 31
40.
Amazing, huh! :P
No you don't.
You need to get rid of your calculator because obviously if it doesn't understand the rules of BODMAS then you need to replace it.
That makes 40. No brackets. By the way, it's impossible for the question to have two different results.
3 plus (7 times 4) is not 31. Okay it is if you use our understanding of maths but it's not logical. The answer is 40 and can never be 31. Putting part of the question in brackets makes a nonsense out of maths because so-called clever people will argue with you and say "well actually it's 31!" when it's not. It's 40.
You can't have one maths question giving you two different results. It's impossible but this happens in maths if some genius (sarcasm meant) decided to add brackets to the equation!
Charming
There do not need to be any brackets in the formula, you just identify the functions that are in the formula and do them in the BODMAS order.
I learned this at the age of 11.
I have an A in Maths at O-level
I have A Level Maths
I am an accountant
*gives up*
Idiot, you're still wrong. It's 40. And if you still doubt me, do the sum on a calculator. The answer is 40. Please do it on a calculator. The result will always be 40. It will never be 31.
If you wish to dispute basic maths, go ahead!
Please tell me why my calculator gives 40 as the result. Go on then, if I'm wrong, why does my calculator give 40 which is the same figure I came up with.
You multiply before you add. The lack of brackets is irrelevant. Brackets just mean that you deal with what's inside the brackets separately. They're not necessary here. You always multiply before you add, add before you subtract and so 31 is correct.
2 + 2 + 2 x 0 is 4, not 0
