What? You're at it again using your sophistry mo to post "When you count your fingers you start with 1 ( and not zero as you suggested I should have done in Octal counting but that is a whole different philosophical debate*)." I never suggested anything of the kind & never mentioned counting on fingers which is obviously counting in tens.exile wrote: ↑Thu Oct 26, 2023 10:29 pm Understanding decimal counting can be difficult because it is so embedded in our culture that we do it without thinking.
We have 10 digits on our hands and that forms the basis of how we count. It does not have to be like that and we could have included another 10 digits on our toes. Perhaps because of shoes, we don't but other older cultures have done so. I am lead to believe that some tribes in Papua New Guinea use a base of 40 - not sure how that works - and ancient Babylonians used a base of 60. ( Throw away useless fact - and that is why there are 60 minutes in an hour.)

You have confused yourself by looking at percentages on your website. Counting in decimal has nothing to do with percentages.
The key point in all of this is that 31 in octal (counting in eights) is 3 x 8 plus 1; and 25 counting in decimal ( counting in tens) is 2 x 10 plus 5. They are the same number.
* Is zero a number?
My point was that ,if counting in Octals ie eights, why did you only mention 1-7 ie sevenths.
Wiki clearly states "The octal, or oct for short, is the base-8 positional numeral system, and uses the digits 0 to 7 " so yes, that plus everything I've ever learned says that zero is a number.

as you know computers work on a binary notation ie 0 and 1. It is cumbersome to write in binary so we often used the octal notation ie a base of 8 or a hexadecimal notation ie base of 16L Austin France wrote: ↑Thu Oct 26, 2023 5:04 pmWell I ain't got a clue wot yer on about so please do explain![]()
So 11 is represented as a and 12 as b an so on
25 is 31 in octal and 19 in hexadecimal
