From an official document published by a large manufacturing company, later revised when I told them about it:-

I think it might have been mentioned in another thread at the time but there was a Co-op ad recently that claimed a bank holiday weekend was a third longer than a regular weekend.

:facepalm:

My company forgot last years promised 6% pay rise so I grumbled. So they said this year they would pay me 6% and 4% = 10% this year. Surely 10% is 6% and 3.77%.

Recently decided to purchase a Jawbone UP24 to do a bit of quantified self-ing (mostly interested in the sleep monitoring / reporting) having got some Love2Shop vouchers to use up.

I then spotted I could order it in to my local Halfords, which meant I could also use my British Cycling discount. Every little helps etc..

List price of £104.99, the girls on the till between them decide to not simply scan in the barcode for the BC discount but enter it manually. I quote: 'So, ten percent of that. That's...twelve pound fifty'.

Nice little bonus for me, just disappointing when it's one of those simple ones to calculate!

From today's Independent.
http://www.independent.co.uk/news/uk/politics/uk-police-shooting-statistics-discharge-firearms-figures-freddie-gray-baton-killings-homicide-a7160391.html

British Police fire guns 7 times in one year.
British population 64M
USA population 319M
Quote
The United States of course has a bigger population than the UK – Britain has 64.1 million residents, the US 319 million. But on a per-capita basis, Britain’s rate of police gun use would translate into US police using their guns on 84 occasions in an entire year. This would be an unthinkably low number.

How does 7 * 5 = 84?

Not necessarily. Depends on how they calculate it. 6% of your salary plus 4% of your pay before the 6% raise is 10%.

Not quite arithmetic, but "it's Thursday, welcome to the start of finals week on masterchef"

The start of a maths lesson, 197{ahem!}; a maths teacher flinging marked homework jotters at pupils.  He arrives at that belonging to a Boy Lurker...

 Boy Lurker!  3 times 3?
 Boy Lurker, rapidly and confidently, six sir.
 *A moment's silence for the awful truth to sink in.*
A pitying look from the maths teacher as the Boy Lurker cringes at his desk whilst his school-fellows pour (well deserved) scorn and derision upon him.

I had made _exactly_ the same error in the homework, I'd done all the hard stuff (chiz algebra) perfectly but stuffed up basic arithmetic.  Over the years MrsLurker has come to recognise that my arithmetic is a little, umm, fuzzy and does our accounts.  It's probably for the best. :)

Even worse (for the customer), something like 'up to -25% discount'. Seen it only once and decided to pass on by.

I've seen BOGOF on eyebrow threading, which makes even less sense than shoes.

Surely BOGOF on shoes, eyebrows and any other obviously pairs are simply an attempt at humour.  I remember the surgeon trying to make the same joke DURING my vasectomy years ago.

To be fair, you don't want actually funny jokes during a vasectomy...

No, TV's Henry Coles, a motorcycle introduced in 1958 is 58 years old.  That, by any stretch of the imagination, is not "nearly 70".

Mrs F was never that much into Numbers and all.
She had to do a Tax module at Law School back in the day.

I remember trying to help out with the basic problem:

If something costs £100, and we add 10% tax, it then costs £110. That's fine.
But why can't I just remove the tax element by removing 10% of the £110?

She's still not convinced about the arithmetic, and suspects alien involvement.

I too am that age and of that vintage.

I am CERTAINLY NOT 'nearly 70'!
