I never realized that some of those calculators you show are more than 100 years old. That's crazy. The fact that you also got the original instruction manual in one piece is also wild. Think about 100 years from now when the Rabbits R1 will be an relic of the past.
Interesting suggestion, I thought about it for a bit and came to the conclusion that If you preform the operation for addition backwards, you subtract. Ex. 24 is the current number displayed and you want to subtract 10. If you start the stylus at the ending notch and move the stylus to the 10 marker, it will unwind to 14.
It's a good thing it's not easy to make mistakes, and with it's compact design you could easily fit it into you pocket (your one foot wide pocket), how neat.
At 3:43 the "add these figures in five seconds" part is false advertising. It would take you about 30 seconds just to add the nine pound values, and that time doesn't even include the shillings and pence, nor the conversions.
They decimalised in 1971, so ever since then the British pound has had 100 (new) pence instead of 240 (old) pence. They never joined the Euro-zone, and as they left the EU that is unlikely to ever happen.
There's a great quote about it on TVTropes under "Old British Money." I can't recall where, but I saw an article not long ago that said some UK accounting software still used the old £/s/d system internally, only rendering decimal output as needed. Meanwhile, here in the US, they priced stocks in eighths of a dollar until 2000, transitioning through sixteenths to all-decimal in mid-2001.
I bought this at a British antiques auction for 88 pounds (incl auction costs), and paid about the same again to get it collected, packaged, shipped and imported.
@@jaapsch2 That's awesome because if I did my math right (always a gamble), when it came out, it cost roughly the equivalent of 1,000+ pounds in todays terms.
@@kenofken9458 You're a bit off there. According to one converter I found, 10s6d in 1910 is the equivalent of 41 pounds in 2017. It may be a bit more now, but not that much more.
@@jaapsch2 I misread it as 10 pounds 6! Now it sounds absurd thinking about it although when the first modern calculators came out they were enormously expensive.

Touché my friend, your comment was just as funny as mine. It makes me wonder if location on planet Earth has anything to do with the level of intelligence. Seriously. It obviously has an effect on sarcasm, people in the USA are way more sarcastic than people in the UK. I don't know if they get it, though.

I am not really impressed. You cannot add numbers larger than 99. You can do that mentally. At home we had a sort of similar device with a stylus, but it could add or subtract numbers of 9 digits or so. And it was more compact.

If they added one more ring of numbers on the outside going from 99-1 you could also subtract. Missed opportunity. Neat device though.

It even has force feedback to notify the operator of overflow!

It's a Pi based calculator!
That is simple and beautiful at the same time.
I never understood the English currency system, and I wonder if they still use it, or have they gone to the Euro?
They decimalised in 1971, so ever since then the British pound has had 100 (new) pence instead of 240 (old) pence. They never joined the Euro-zone, and as they left the EU that is unlikely to ever happen.
@@jaapsch2 I agree about the not joining the EU, and I didn't know they had updated the money, cool!
They decimalised it some time ago, abolished shillings, and converted pounds to have hundred pence each.
they replaced the confusing standard with an arguably less confusing one but still was to british to adopt the euro

Very neat
Was it possible to move it in reverse direction for subtraction, or was it addition only?
Do you share the price you paid for the items?

should also be noted that it can be used to subtract as well, if it adds then it subtracts too since they're kind of linked.
It also will do division of whole numbers
