Imagine if Americans switched from using pounds to kilograms over night.
There would be mass confusion.
Worse still, imagine trying to explain to them that neither is the right unit for weight.

They would suddenly go from 220lbs to 100Kg and think they were instantly slimmer.
It would cure the obesity problem overnight.
Doubt that would go down well either side of the Atlantic.
This is pretty damn amazing. Mine turned out to be"Raiders of the Lost Ark". I was surprised how this worked.

Now, ainât that somethingâŚ?
NO
Spot on
Ha - Mine efforts calculated out to number 9
They all do
Thats spoilt it. I was just about to order it.
This is where it gets a bit trickier, but just hang in with me. Letâs call our two digits A and B (so if our number was 36, for example, then A would be 3 and B would be 6). So our number is 10 times A plus 1 times B (e.g. 36 is 10 times 3 plus 1 times 6), which is 9 times A plus 1 times A plus 1 times B, which is 9 times A plus 1 times A+B. This total must be divisible by 9 (see our proof in bold, above). 9 times A is definitely divisible by 9, so 1 times A+B, which is just A+B, must be divisible by 9 too. Because Adam restricted our very first choice of number to be from 1-9 it turns out that when we divide A+B by 9 we always get 1 i.e. A+B is always 9.
This is the basis for the trick which allows you to work out whether any number is divisible by 9 - you just add the digits together, and keep on adding the digits of the result together until you get down to a single digit. If the answer is 9 then the original number was divisible by 9. If itâs not then it wasnât. The same thing, more or less, works for 3 too.

So âThe Joy of Anal Sex with Sheepâ is not really my favourite film ?
I think youâll find it is.
Be careful how you wrap!
