Intelligence on the internet

Scott, you need to understand the difference between "convention" and "objectivity"/"a priori". This seems to be where you're losing my point.
Again, I'm not saying BODMAS doesn't exist as a conventional rule.

I'll say this again...Just because someone doesn't know/use/implement the rule doesn't mean that it doesn't exist.

Can you actually read?

No, I just randomly kit keys on the keyboard to reply.

To be frankly honest, I would be better off.

rule/law

I was basically tongue in cheek, pointing out, without brackets, obey Bodmas

The whole reasoning for it being on Facebook? Who knows, it's probably so that after several thousand, like, shares, comments, in a few weeks people will notice adverts for 'Arse Tickler's ******* Fan Club'

Maths doesn't use logic, it uses, erm maths

Where's that wall again?

 

[Russ146]

Bodmas only works without brackets if the sum is in the right order

i will stick with common sense and a trusty honest calculator like the rest of the Planet

Its 18.

Are you serious?

As long as Common sense is....


Bodmas ALWAYS applies

Bodmas does not need to be written in the right order, Bodmas is there so you work out the order...

Quick test here, got a mobile phone?

My Samsung S3 built in calculator gets 12 as the answer, my built in PC calculator gets 18

I shall stick with the S3 calculator in future as it is correct

Are you serious?

Yes,
25% of 100 is 25 which is maths
2x2 is 4 which is maths
3+3x3-3+3=12 it is maths, it obeys BODMAS
(3+3)x3-3+3=18 it is maths, it obeys BODMAS

And I shall use common sense to give up saying 18 is wrong!!

 

[jarenault]

Unbelievable.

 

[MadrikXIV]

Unbelievable.

Really? Just simple maths, nothing logical

3x3+3-3+3=12
3+3x3-3+3=18
3+3+3x3-3=24

etc

As you can see from the above, the same equation gets 3 different answers.

Sorry Scott that's 3 DIFFERENT equations hence 3 different answers

The answer is 18. end of

Gotta love the S3, it got these right everytime....
12, 12 and yup 12 :clap:
Anyone got an iPhone with it's built in calculator, just out of curiosity

 

[jarenault]

Okay. Okay. You're winding me up. I was falling for it there.
"Maths isn't logical". Hahaha. Good one.

Maths has rules

Unless you want to include the 'Logic' of using Bodmas in the simple original sum

What exactly are we trying to prove here?!

That I should have paid closer attention at school.

 

[oldbloke]

Some devotees of the Lambda Calculus will tell you that mathematics is founded entirely on Logic.

I prefer to start from the Calculus of Indications as a foundation for both.

 

[jarenault]

I'm out. There's clearly no comprehension of the point I was trying to make.

Wise words, mate. I've got a degree in maths, but I chose to look that up Google, just to annoy people.

I started a degree in Stats, but never finished it. The 1970s for you there.
Before Google we used to look things up in The Whole Earth Catalog
That's where I discovered the calculus of indications in G Spencer-Brown's Laws of Form

I have to say that this thread has been great fun reading :lol: :lol:
Never heard of BODMAS before, I always thought the multiplication should be in brackets. I did get the answer wrong the first time I read the question but after reading the links Scott posted I get now why it's 12
P.s My Galaxy Ace 2 calculator gives 12 as the answer too :thumb:

 

[oldbloke]

I never got taught BODMAS (as far as I recall), I just got taught the correct order for applying things - I never did get on with mnemonics, found it easier to just remember stuff.

Yup mine too. I got it right when I first saw it but only, like oldbloke, because I knew to multiply first. I could just as easily have gotten it wrong. The comments that followed mentioned BODMAS, I couldn't really recall what it was so I looked into it and since then it's stuck lol.

I'm fairly certain I did, but it wasn't a big deal from what I remember. We were taught, like yourself, the order of things. BODMAS was probably in the lessons at the beginning but not referenced frequently enough for it to stick.

 

[MadrikXIV]

It's odd, I dunno why I remember it being called Bodmas, but it stuck, and since then, ermmm until the Internet appeared with the what does this equal, I doubt I have ever had to use it

 

[cutnrun]

The reason i remeber it is a little odd but we were taught taught about an American Indian called BODMAS

No idea why but the picture of it has stuck in my head and I follow it as a Rule/law of maths


ps the Iphone calculator is a bit useless however i get 12 when i put it in... in the correct order.
