how is the number system with base 8 called?

Answer 1

A base-8 system (octal) was devised by the Yuki of Northern California, who used the spaces between the fingers to count. There is also linguistic evidence which suggests that the Bronze Age Proto-Indo Europeans (from whom most European and Indic languages descend) might have replaced a base 8 system (or a system which could only count up to 8) with a base 10 system. The evidence is that the word for 9, newm, is suggested by some to derive from the word for 'new', newo-, suggesting that the number 9 had been recently invented and called the 'new number' (Mallory & Adams 1997).

So what if we had eight fingers, or for some other reason, we decided to start over every eighth number instead of every tenth? Then we would have "base eight" (also known as "octal") counting. In this system, there are eight symbols to work with:
0 1 2 3 4 5 6 7

We don't need an 8 or a 9 at all: out of just those eight symbols above, we are going to represent every possible number! So, we start by listing all the symbols after the "zero."

what does 1235 base eight really mean?
it is 5 "ones", 3 "eights", 2 "sixty-fours", and 1 "five-hundred-and-twelve." If you add all that up,

5*1 + 3*8 + 2*64 + 1*512 = 669

So we can say "1235 base eight equals 669 base ten." Or, to put it another way, "when you write 1235 in base eight, you really mean the number six-hundred and sixty-nine." That's a kind of base-ten-centric way to put it, but hey, we're base-ten-centric people. And in any case, the point I'm making is that it's easy to convert base eight numbers into their base ten equivalents, once you understand the system.
