TMS Year 4 Maths Question

[Big Bad Bob]

 

This is going to rival Bearsy's new novel, esp when the maths teachers get involved

[sandwichsaint]

I'll go first BIDMAS = 9 ?

[Whitey Grandad]

Imprecise

[Smirking_Saint]

Is it 3

[Cascadia Saint]

1. Probably.

[biondani]

1. 6 / 2(3) ie 6 / 6

[Seaford Saint]

You work out what's inside the brackets first, I think...so 1+2=3 6/3=3. So 3x3=9

 

But it was 45 years ago

[CB Saint]

Ill go for 1

[ecuk268]

Brackets first so 1.

[jjsaint]

I'm going number one as well.

[dubai_phil]

Nope. Sorry.

 

Still haven't been able to find a 4 year old to answer this for me

[Saint-Reece]

6/2(1+2)... 6/2(3)... 3(3).. so i'm going for 9

[Saint-Reece]

That is by using BIDMAS btw ^^^

[KelvinsRightGlove]

Nope. Sorry.

FFS year 4 & 4 year old are completely different things.

[Big Bad Bob]

Nope. Sorry.

Year 4 is 8-9 year olds.

 

And the answer is 9

[Window Cleaner]

Year 4 is 8-9 year olds.

 

And the answer is 9[/QUOTE]

 

 

why ? looks like it should be 1 to me but perhaps this is a new system used to calculate state benefits or something like that.

6/2(1+2) is the same as 6/2*(1+2)

 

So, according to BODMAS/BIDMAS/PEMDAS, do the brackets/parentheses first :-

 

6/2*3

 

In BODMAS/BIDMAS/PEMDAS Division and Multiplication have the same precedence so you work from left to right, in plain English this becomes 6 divided by 2 multiplied by 3 which is 9!!

 

Seemples

[CB Saint]

Big bad is right

 

Brackets

Powers

Multiply and divide

Plus and minus

 

Multiply and divide rank equally therefore you go left to right

 

Now I know why I quit maths

[CB Saint]

Beaten to it

[Smirking_Saint]

Lol I have a degree in electrical engineering which is pretty much pure maths

 

Major fail

[Dimond Geezer]

Using BODMAS I get 9 (the correct answer), worryingly my calculator gives 1.

[Tokyo-Saint]

372 remainder 4 give or take the odd 5 here or there?

[John Boy Saint]

If 9 is right then I didn't widdle 10 school years of maths up the wall afterall, and it stayed in for another 33 years!!!

if it's wrong then loading the chalk holder of the roller board in maths with those paper twist fun snaps so that they all went off when Mr Robinson pulled the board down showed that my time was far better spent in physics!!

[Tokyo-Saint]

So you start school at 5 years old, JBS did 10 years of school meaning he left at 15 years old (drop out!) and it is 33 years later so.... JBS is 48 or have I got the maths wrong?

No, you start school when you're 4 unless your birthday happens to be in the first couple of days of September and then you'll probably be 5.

 

You can leave school at 15 too, if you're birthday's in July or August.

 

Either way JBS' memory is failing him, however he is more likely to be John Grandad Saint

[Tokyo-Saint]

Yeah but from what you are saying, unless his birthday is early September, he dropped out when he was 14. That is worse than bear!

[Whitey Grandad]

Using BODMAS I get 9 (the correct answer), worryingly my calculator gives 1.

 

Yes, it's imprecise. In such circumstances I would always put extra brackets just to be sure.

[Bearsy]

hi i've just noticed this thread. I calculate the answer is 9, i done this by applying DUMAS. What is everyone else get?

 

edit - i think it is imprecise tho i would put extra brackets, you is never have enough brackets

[John Boy Saint]

Excellent work Tokyo, and BBB highlighted an error in my own workings out. But then having had a birthday in the last month I forgot to add a year, in the days of black & white you started school at 5 and I left at 15 when my CSEs were finished in June and as my birthday is in August I became the last of the kids with a push bike when my mates all had Mopeds

 

Went to college............ Christ knows why as I dropped out of that.

[sandwichsaint]

Chuffed with that, I didn't do any maths beyond O Level in 1976, just know BIDMAS from a bit of primary school TA-ing 15 years ago, not that I particularly understand it.

[bridge too far]

Never heard of BIDMAS - just worked it out as I would have done 50 years ago and got.......... 9! Yay, go me

[mcjwills]

Made it 9 via Bidmas and the calculator on the samsung phone also made it 9.

[Tokyo-Saint]

What the **** is Dumas? I made is 9 by just working out the outside stuff times the inside stuff. Are teachers on strike so much these days people don't get that?

It should be 'dumbass', unless you are talking about the great French writers.

[Tokyo-Saint]

Bit xenophobic whitey, sure some French are dumbasses but surely not all of them and not all their writers? They are not actually writing in English and doing it wrongly, that's their language dude.

Au contraire, mon ami. I was saying that the Dumas father and son were great literary proponents.

[Tokyo-Saint]

Which dumbass father and son?

[Whitey Grandad]

Alexander Dumas, pére et fils. The Count of Monte Cristo, The Three Musketeers, and much more.

[Saint Garrett]

Definitely 1.
