"five and sixty thousand five hundred six and thirty", right?

Dutch is similar and this is a source of mistakes when writing down (phone) numbers. I've resorted to calling out the digits in LTR order.

Norway used that as the standard order until 1951, when an official reform changed the language to LTR. This was due the older way of stating numbers causing confusion when reading phone numbers and similar. It's still not universal, but younger generations generally now state numbers universally left to right.

There’s examples of it in English too, although it’s very old-fashioned. An example would be the rhyme with “four and twenty blackbirds baked in a pie”.

Correct. The grouping matters, and double-digits in groupings are also reversed - "fünf und sechzig tausend fünf hundert sechs und dreißig".

Another thing, years in German aren't spoken as "twenty twenty-one" as we commonly do in English, but instead the number is spoken out fully - "two-thousand one and twenty" ("zwei tausend eins und zwanzig").

In England, the little voice in Google Maps told me to take the "B one thousand, one hundred and thirteen", when every human i know would call that road the "B one one one three".

[PennRobotics]

Ah right. My mistake. It would be five and sixty thousand ... Yuck!

I guess this is exactly what we're talking about---mistakes because you are not natively familiar with a particular system, and then you miss the non-base case. For me, I got the tens digit right but not the ten thousands digit.

In the memory case, it's knowing to change a pointer location because an address to a 32-bit value will start or end at a different address than a 64-bit value.

I totally hate people who repeat a phone number back to you, but with different digit grouping. How the hell am I supposed to know if that's the same number!? Just repeat it as I said it already...

[__del__]

numbers grouped in twos are great for mnemonic memorization. you'll easily come up with an association for many two digit numbers.

ex. 415-222-9670 becomes: sub universal (one less than the answer to life, the universe and everything) deck (52 cards) swift (she's feeling 22) resolution (old dpi on wandows) top speed (California speed limit)

now isn't "sub universal deck swift resolution top speed" easier than googling twitter hq? ;] granted, the associations have to make sense to you. for me, 96 was a toss up between nashville (code name of windows 96) and the resolution i had to train myself to remember after moving from the mac's 72.

I just can't write down phone numbers when people pronounce them that way. "Nul vier­honderd­vijf­en­zeventig twee­ën­tachtig zes­en­dertig een­en­negentig"? You lost me at nul.
