discuss..

Depends on if you are seperating the numbers out (brackets etc) as to what answer you get.

there are no brackets in this equation :)

Fair enough. Pretty straight forward then.

thats what i thought! :grin:

It was never my strong point at school... :undecided: :embarassed:
-
With a bit of jiggery pokery I can also get 20. :grin:
-
You multiply before you add so there is imaginary brackets there

Did Alevel maths last year but i bet i still get this wrong

ya. 21. ( :undecided:)
-
Ah bolocks. i thought it said 20x20x0+1 so i voted for 1 as 20x20x0=0
-
20 + (20 x 0) + 1 = 21
(20 + 20) x (0 + 1) = 40
I looked at it like this:
((20 + 20) x 0) + 1 = 1
Not that simple.. :grin: :grin:

If you put brackets in, doesnt that make it a different equation :rolleyes:

What's to discuss? It's a simple question.

You cant add 1 to nothing!
Because you have nothing to add to.

I want this as my sig! :grin: :grin:
I think you mean multiply.
-
20 + 20 = 40
40 x 0 = 0
0 + 1 = 0
-
20 + 20 = 40
40 x 0 = 0
0 + 1 = 0
BODMAS clearly ignored here

Also 'zero' as a true value never actually exists, even if it is 0.0000000000000000000000000000000000000001 or whatever so 'zero' is a concept and not a value.

So if you have 0 money in your bank but then pay in £10. They swallow the £10 and leave you with £0 in your bank as you cant possibly add to 0?
I need to open a bank on this rule.

So who voted 1 then?

They were discussing this on radio two yesterday, unfortunately I wasn’t paying any attention, I made it 1 and then checked it on the calculator which also makes it one. I take it that is not the right answer if so please put us out of a misery. :undecided:

:smiley:

I dont understand why brackets are being added when there were none in the original question, how is the answer not 1?
20+20 is 40, then times 40 by 0 which is 0, then add 1, which makes a total of 1. Is that not correct? This could be fun with some of the smart arses at work :evil:
-
As said just because the brackets are there doesn't mean the rules of mathematics shouldn't be followed..it's not 20+20.....
-
the rules of maths are silly
-
Regardless of them being there or not, it's always multiples before additions.
Even putting it in to a calculator brings it out as 21. :smiley:
-
this forum has taught me more than several years of schooling :tongue:
-
my calculator brings it out as 1 :undecided: Not saying anyone's wrong but it goes against what I was taught at school (at least what I can remember of it 12 odd years ago :laugh:)
I know this is being called simple maths, but if certain calculators bring it out as different answers and calculators are what kids are relying on nowadays in their exams, doesnt seem very simple to me :tongue:
-
The normal calc returns 1, the scientific calc returns 21, programmers calc returns 10101. Sure we learnt this at school, the last time I would have done something like this would have been 12 years ago, not going to have remembered that little quirk of maths rules straight away so went for the obvious answer, I did try change my answer after a minute as I had remembered the rule but it's not set to allow changes.
-
multiply first... give you 21. Which was my answer :nerd:
-
Its 1 20+20 x0 = 0 + 1= 1 this is very simple lol
-
Its 1 20+20 x0 = 0 + 1= 1 this is very simple lol
which bit of multiply first did you not get :rolleyes:
-
21.
Follow the rules of BIDMAS people. I've been teaching it for the past 13 years :laugh:
-
Its 1 20+20 x0 = 0 + 1= 1 this is very simple lol
which bit of multiply first did you not get :rolleyes:
I don't believe this rule in this equation either way i look at it nothing multiplys into zero so i'm left with one and im sticking to my view at looking at this although i might vote for 21 just incase :grin:
-
I got 11.11.11
-
Screw all this rules of maths tosh I'm sticking with my original answer of 1!

I got 55378008.

lol @ this thread... I wasn't expecting so many weird and wonderful answers
but as has been said.. BODMAS / BIDMAS is the answer :cool:

Len, that is truly astonishing :huh:
I really, really hope that you come back to us and say.. 'only joking.. see I had you all going there lol'

:grin:
-
So who voted 1 then?
ill take part of the blame for that :lipsrsealed: however as soon as i clicked it i realised it said 20+20 not 20x20
-
What was the question again?
Thom
-
What was the question again?
Thom
What's 1+1?
-
As regards to the maths exam question, if you just said you put 20 + 20 x 0 + 1 in the calculator and showed that in your workings out you would lose marks.
You have to do it properly. Then you will get the same result. Traditional calculators will just automatically "equals" when you hit + - / - etc.
-

Thom

Apple :grin:
Thom

I like the fact that since I asked who put 1 as the answer, clearly displaying that as the wrong amswer, another 14 people have voted 1.
You are all doomed.

i said one

I would just like to add that currently 79.8% of you are stupid. :smiley:
-
Its a trick question really, i did A level maths, but it was 20 years ago :grin:
It should really be written as 20+(20x0)+1=21
-

It should be, but as it isn't the rules still apply. Of course adding your own brackets to the equation can give you a different answer.

Yes, i don't remember that rule, as i said its been 20 years :embarassed:
From a logical point of view, and to be totally clear, it should really have brackets.

but I bet they would however, know that 0 + 1 doesn't in fact, actually equal 0.

that has to have been a typo!! surely even in the 1800's the education system taught them better than that :huh:
Is Len going to come back and explain at any point?? :lipsrsealed:

You lot are mathematical bullies :laugh:

You lot are mathematical bullies :laugh:
fark off!! its not our fault they never paid attenshun at skule :grin:
i am truly astonished by some of the answers though...
1 56 (56%)
21 19 (19%)
0 3 (3%)
40 5 (5%)
41 17 (17%)
25% of the respondents need a little bit of extra maths tuition... please stay behind after school! :smiley:
-
I was one of the 19% :)

Jesus who thinks it = 0?
I'm a tad shocked but brackets would boost that IQ level up a tad!

Keep up at the back!
You cant add 1 to nothing!
Because you have nothing to add to.
20 + 20 = 40
40 x 0 = 0
0 + 1 = 0
Remember forum friends, if you are out tonight and have had say, 0 pints, that if you go to the bar and get yourself 1 pint, that you then proceed to drink, you will honestly have then had in total, 1 pint. Not 0, definitely not.

I've heard that before, but it only makes sense verbally and in this case to do that correct math you can view doing the equation back wards to make more sense to peeps!
Len look at it this way.... if you have one then add nothing you are left with one
1+0=1
20x0=0
1+20
left with 21

This thread is like being at work with my kids! :angry:
Look up and use BIDMAS folks!
I charge £30ph for private Maths tuition, but I'm happy to knock that down to £25 for fellow forum users :laugh:
-
Ive got two kids and one is Autistic he struggles with Math and reading is hard for him, but instead if learning the usual way I have to impliment strategies so he can remember and work the answers out correctly even though its frustrating.
AND do I feel bitter about having to prop up his education because the schools are failing him YES! :cry:
-
or look at it like
I have 0 cars.
I bring home 1 car.
I have 1 car. not 0 cars :grin:
I'm looking for a MK1, so to justify this, I'm going to add one car to another = still one car :laugh:

If you get pulled by plod and he asks if you had a drink you can just say you had 1, but because you can't add that to 0 then you've had nothing. Len maths = no DUI :smiley:

I'll stick my hands up and admit I put "1". :embarassed:
I didn't look through the posts before I worked it out (didn't want to cheat). As for my technique, I just read it as it appeared and forgot about the BIDMAS (or whatever it's called).
Maybe need a new option for Len though on the poll.
