Why do they go in tens?
I mean when you think about it, what is ten? What makes it so much more important?
It could just as easily go:
1, 2, 3, 4, 5, 6, 7, 8, 9
11,12, 13, 14 15, 16, 17, 18, 19
21, 22, 23, 24, 25, 26, 27, 28, 29
etc..

Im not confused.I'm actually going to assume it goes up in tens because we have ten digits and it makes it a shit ton simpler to teach. It also couldn't go like that, the system wouldn't work without zero as a placeholder!WhosZena? wrote:Numbers...

edit: Now that I've thought about it, I want to know how the ancient Romans handled doing math. Equations made up of roman numerals would have been just a mess
They still did math pretty similarly which is just boggling! One equation could quite literally take your entire life to figure out.WhosZena? wrote:I see what you mean about zero.kidshuffle wrote:I'm actually going to assume it goes up in tens because we have ten digits and it makes it a shit ton simpler to teach.

The Romans probably didnt do their equations in the same way, or they had bigger brains.
Wicked, Im a bit of a geek when it comes to numbers and patterns etc. I start thinking about it all and get lost in my thoughts.kidshuffle wrote:They still did math pretty similarly which is just boggling!

I was actually talking to my roommate about the importance of zero/going up in tens the other day. He's getting his PhD in Philosophy so he had a lot of good stuff to say about it, I'll try and get some other info about it because it was really interesting.

Without the zero, you're forced to change a number's face value... 10 = 1 x 'column of ten' and 'zero' in single digits... If it went 7, 8 ,9, 11 for example, '11' would be used instead of ten, meaning that the arbitary value of '1' has been altered... You can use other numbers as the base (noteably 6 was frequent before ten) as long as principles are followed. Consider it as counting in a tally system, it's the quantity that reveals the 'number' and not the way in which they're recorded. It's a useful labelling sytem that aids in keeping numbers infinite, rather than the arduous task of generating a specific symbol for each number

With our number system they all seem different, if someone swapped 6 and 7 it wouldnt really make a difference we would just all re-learn the value.
But if they swapped (IIIII I) and (IIIII II) it just wouldnt be right.
But it still doesn't properly answer why they are grouped in 10s... And about now is when my thoughts get very annoying.
Have fun with your ducks.
I never thought of it that way, thats actually pretty true. And I asked my roommate about it, and he said the accepted theory is that we have groupings of 10 just because of thats how many digits we have, so it just seems like the natural way to do it. Apparently some ancient number systems go up in 5s and 20s too.WhosZena? wrote:
