I had an old, ratty denim Dickies coat with thick insulation that probably weighed six or seven pounds. I’d throw it over a few water bottles on the floor or the seat, and they’d still be cool when the ones exposed in the backseat were warm, almost hot. Seriously, I had better luck with that coat than I had with coolers without ice.
Yeah, why do you ask out of curiosity? I guess my interest is because I’m a cs/math student so I’ve been dealing with number theory a lot the last few years.
Also I skimmed the rest of the article, and to me it looks like wikipedia editors have actually been very careful not to conflate numbers and numerals, so I’m not sure what you mean. In fact, under history>numerals it even says “Numbers should be distinguished from numerals”
Huh? I didn’t miss it, that line is exactly why I’m even having this discussion with you
You have 10 numbers (or cyphers/digits)
I’ll say it again, because I think you missed it, numbers are not cyphers or digits, and the terms can’t be used interchangeably unless you can only count to 9. Since you brought it up, the first 3 lines on the numbers Wikipedia page:
A number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, 4, and so forth.[1] Numbers can be represented in language with number words.
By its definition, there are infinite natural numbers, but all types of numbers are infinite in quantity. When you say “number”, you seem to be thinking of what Wikipedia calls “number words” or “numerals”, or the terms “digits” or “cyphers” that you brought up. Those last four terms are components of language, they can represent numbers, but in the context you provided (“You have 10 ____”), you really shouldn’t have used the word numbers.
TL;DR, digits are to numbers as letters are to words. There are 10 digits (in base 10), and 26 letters (in English). There are infinite numbers, and there might as well be infinite words
The math is the same, you just wrote it more “casually”. For me it was 0+100, 1+99, 2+98 … 49+51 -> 100 x 50 = 5000, then add the 50 that was missed from the middle for 5050. But yeah I remember coming up with that when I was really young.
