Have Nationwide online Accounts?

I have accidentally stumbled upon the fact there is a potentially serious flaw in Nationwide's online banking UI and processes, it is presumably already known to others. It isn't a security problem. If you have to file an Income Tax Return with HMRC and use online Nationwide interest bearing account...

Re: The BODMAS mathematical rule.

The computer scientist in me is saying that spaces aren't significant, other than as separators when necessary (and obviously not necessary in this case). ... I stand by the first part of the post though. Yes, a computer would ignore all the spaces. But a human likely wouldn't. To a human (at least...

Re: The BODMAS mathematical rule.

The computer scientist in me is saying that spaces aren't significant, other than as separators when necessary (and obviously not necessary in this case). So 6 / 2(2+1) is the same as 6/2(2+1) and 6/2 * (2+1). If BODMAS didn't mean D before M and A before S, there wouldn't be much point to it. So p...

Re: Format of Old TV programmes

Blimey! Result!

It's just come back from an ad break (in widescreen, obviously) and is now displaying in widescreen - 14:9 in my case.

Weird...

Format of Old TV programmes

I know I have asked a similar (possibly even the same!) question before, likely on TMF... I am watching The Bill (Again?) on Drama. They are from around 2001. I'm watching on an old 4:3 CRT receiver (not sure that's important) with a digibox set (still) to normally display in the compromise 14:9 for...

Re: The BODMAS mathematical rule.

My hand calculator says it's 1. My Windows Scientific Calculator won't commit itself... Actually it gives 2, as it throws out the first 2 to evaluate 6/(2+1), with a chained calculation. Of course, if you calculate intermediate results.. Actually, if you calculate intermediate results left to right...

Re: The BODMAS mathematical rule.

The OP clarified his OP here https://www.lemonfool.co.uk/viewtopic.php?p=185744#p185744 The formula is (6/2)(2+1) The answer is nine. Fools have been carrying on regardless. ;) Yeah.

Re: The BODMAS mathematical rule.

1. The clickbait article linked to contains items of complete nonsense. Even that article, after declaring the correct answer to be '9', goes on to declare that it could also be '1' if you were using an earlier in the 20th century interpretation of BODMAS! As an aside, I can't even remember BODMAS ...

Re: The BODMAS mathematical rule.

Re: The BODMAS mathematical rule.

With these values for a , b and c , what I am saying through my inequality is that 6/2(2+1) is not the same as 6/(2(2+1)). But, as they are different expressions - with the first seeming ambiguous and the second being unambiguous - how does that help? 6/2(2+1) is 9, whereas 6/(2(2+1)) is 1. 6/(2(2+...

Re: The BODMAS mathematical rule.

Putting =6/2*(2+1) into excel gives the answer 9. You think that's a recommendation? :) The Windows(8) Scientific Calculator refuses to even enter it as given (probably wisely). My hand calculator gives the answer as 1. :shock: P.S. But you haven't gone with the original expression, which I did abo...

Re: The BODMAS mathematical rule.

Can a Mathematician put me out of my misery? I've been following a discussion on a Facebook group about the BODMAS rules, i.e. the order in which mathematical functions should be performed: Brackets..Order...Division etc. The simple sum causing confusion is: 6 / 2(2+1) = ? Obviously the / is the sy...
