Something like rounding is not done very often for most people. Maybe the nearest they come is just rounding up a restaurant bill, and that's to no specific rules.

So, when a question like this arises, I can sympathise with someone giving it a bash and believing it to be correct. It's just lack of practice.
Even the idea of rounding up from the least significant digit is 'almost convicing' when it's just 3 digits or so.... until you think it through and figure it can't be right if there's 400 digits!

You get the same with physics where some explanations are so plausible, you almost start believing them yourself (if you jump up during a flight, you'll end up at the back of the plane!). Complete bollocks of course.

Those of you with the pecualiar idea that you go all the way to the right and then work your way back, can one of you please round pi to one decimal place for me? I’ll wait..

Sorry torn, I think your solution is irrational.

TornFromTheInside · 20/01/2019 22:56

My number's up!

Happy days :)

Grin I do love a maths thread where after a Cambridge mathmo has posted the correct answer, with an explanation, people still argue the toss.

But surely if your maths is so poor that you cannot get the correct answer (but are trying your best), then why respond to a maths question.

Especially on MN where mathematicians are like double decker buses, wait a while and three will turn up at once.

5 out of 4 of us struggle with maths.

I’m expecting a second thread at this point.

MN has a disproportionate number of mathematicians compared to the general population. I should probably out myself as a physics graduate but I’ve still got some game.

Learn something new everyday..I thought the o in bodmas was off...as in Brackets Off...

LivLemler · 21/01/2019 07:42

Banana some would say the O is for Of, as in Power Of.

I don't think I've seen him here yet, so I'm going to tag @DadDadDad just for the lols.

Drogosnextwife · 21/01/2019 08:04

It's 13.0

OhDearGodLookAtThisMess · 21/01/2019 08:06

Drogo, Are you taking the piss?

StealthPolarBear · 21/01/2019 09:04

I was told brackets over division multiplication addition subtraction. I always assumed the 'over' meant 'in advance of'.

ThumbWitchesAbroad · 21/01/2019 09:09

I think Drogo is guilty of "cancel the cheque"itis.

ThumbWitchesAbroad · 21/01/2019 09:14

SPB - no, the O is a specific operation in its own right - orders, powers, indices or whatever else you want to call them are squares, cubes etc., i.e. 2², 2³

Dowser · 21/01/2019 09:16

In my book...it’s 13

ThumbWitchesAbroad · 21/01/2019 09:17

Your book is wrong.

StealthPolarBear · 21/01/2019 09:18

I know what they are, I'm just saying that's what I was taught at school.

OhDearGodLookAtThisMess · 21/01/2019 09:20

What book is that, Dowser?

TornFromTheInside · 21/01/2019 09:20

It wasn't a maths book, that's for sure

ErrolTheDragon · 21/01/2019 10:08

The correct answer (12.9) has been provided by primary school teachers, maths tutors, maths graduates, a maths lecturer.

You'd better return that book as faulty.
