Actually, those are not the same. Natural numbers include zero, positive integers do not. She shoud definately use 'big naturals'.
Edit: although you could argue that it doesnt matter as 0 is arguably neither big nor large
Natural numbers only include zero if you define it so in the beginning of your book/paper/whatever. Otherwise it's ambiguous and you should be ashamed of yourself.
Fair enough, as a computer scientist I got tought to use the Neumann definition, which includes zero, unless stated differently by the author. But for general mathematics, I guess it's used both ways.
Natural numbers include zero
That is a divisive opinion and not actually a fact
Yeah, it's a matter of convention rather than opinion really, but among US academia the convention is to exclude 0 from the naturals. I think in France they include it.
positive interers with addition are not a monoid though, since the identity element of addition is 0
Okay
I hope that explains everything
They're not a complete algebraically closed field either, but I don't see you advocating for including e - i in the natural numbers!
Big naturals in fact include two zeroes:
(o ) ( o)
Spaces and parens added for clarity
Depends on how you draw it.
Natural numbers include zero
Only if you're French or a computer scientist or something! No one else counts from zero.
There's nothing natural about zero. The famously organized and inventive Roman Empire did fine without it and it wasn't a popular concept in Europe until the early thirteenth century.
If zero were natural like 1, 2, 3, 4, then all cultures would have counted from zero, but they absolutely did not.
american education system moment?
I think round the world, children and adults start counting from 1. It's only natural!
I think about this in terms can I have of something (indivisible), and sure enough I can have 0 apples (yeah, yeah, divisible), bruises, grains of sand in my pocket
Also in an aqueous environment, they become floating point values.

Like that?
Oh wow. Do we have a lemmy community for that?
be the change you want to see!
Big Naturals Are More Pronounced
ftfy
Don't get me started on the unnatural and supernatural numbers.
Sound made up, like imaginary numbers.
I mean all numbers are made up when you think about it.
Also unrelated but natural numbers are closed under multiplication (by pure coincidence) while imaginary numbers are not.
This means natural numbers make worse examples when learning about sets.
Made me think of how everything is base 10, even octal or binary.
I don't care if they're big, as long as they're real
I don't care if they're real, as long as I can manipulate them
They're Real, and they're fantastic.
You like big figures and you cannot lie?
Imaginary ones are useful too.
This actually got a chuckle out of me. Prob the first number related joke I've laughed at.
I like naturals, but more than a mouthful is kind of a waste. ;-)
That's true OP, "big naturals" are indeed very pronounced.
I googled "Big Naturals". Result number 16 was this:
Should've been number 1.
Natural Numbers ≠ Integers though.
In spite of that, I'm chuckling. Math can be funny sometimes 😂
Positive integers are (a subset of) natural numbers
Why a subset? They're the same thing right? I guess it could be about the zero?
you answered your own question
Well what I learned in school was that zero was both positive and negative. I knew some people consider the natural numbers don't include zero, but I didn't know for some zero isn't even positive.
it is neither positive nor negative
I knew a physicist who considered 0 negative if she arrived at 0 coming from negative source numbers and positive if coming from positive sources.
Something something sampling rate
Some places (like France) talk about positive and strictly positive, others (like England) about non-negative and positive
I just say “big’uns”
we like to see those Double negative intergers.
Why, would anyone at all think about something else?
