Two different calculations: 342 -173 =169 342 -173 =147 So which one do you prefer? ------------- He say nothing is quite what it seems; I say nothing is nothing (Peter Hammill) |

They are both correct.

In that case I vote for the one which is most correct: 169. -------------

You don't have to be great at maths to know the answer.

Is it any wonder the Greek economy is in the situation it is with math like that?   -------------

I’m not Greek, and as far as I know the Norwegian economy is quite strong.

You know it was a metaphor meaning to say I was rubbish at maths and I actually do need explaining to get it.  I'll let you guys have a bit more fun then I'll be waiting to be enlightened. :P I suppose it's all about "reading" it not like a subtraction but something else (which would explain the possibly eccentric position of the minus), but I don't know any other way to read it. |

Thanks! That was my goal with the poll! Actually, I was inspired by all the Genesis/Yes/Rush polls we’ve seen recently, and even more by the Suggestions thread in Just For Fun. @Alex: It’s a song by Tom Lehrer. It’s called New Math, and I posted a link to the lyrics in my last post. ------------- He say nothing is quite what it seems; I say nothing is nothing (Peter Hammill) |

It's addition/subtraction in base 8, which means the only "numbers" you have available to you are 0 through 7. So in base 8, 7+1=0, 7+2=1, 7+3=2, etc. You can google modulo arithmetic to learn more.

No problem. Actually, I need to amend my example- it's 7+1=10, 7+2=11, etc. Once it "overflows" you get another digit, just as in base 10, 7+3=10.

You must have. Surely you have heard of binary? Which is base 2. I think. You can have a system of any base including letters. ------------- http://www.last.fm/user/Snow_Dog" rel="nofollow">

| ^ Never. As for binary, I always thought it is a language that works based on the positioning of 0 and 1 inside sequences, I didn't know it also allows operations. Maybe that's something else, not "binary"? |

Binary is just the base 2 representation of a number, with operations similar to what I described earlier. For example, in binary 1+1=10. 10+10=100, and so on.

Then there are bases greater than 10, like hexadecimal (base 16), where 9 + 1 = A.

We also use a duodecimal system (base 12) every day: The calendar has 12 months, there are 12 hours on the clock face, we talk about dozens. I don’t know if "The Twelve Days of Christmas" fits in here, though.

The best example is probably a sexagesimal (60) system which we adopted from the Babylonians. You see remenints of it in our clocks and our measurement of angles. Though, our modernization of it still uses the arabic basic 10 system so it is not truly sexagesimal. ------------- "One had to be a Newton to notice that the moon is falling, when everyone sees that it doesn't fall.

You can. A base "n" system merely is a way of writing a number so that the digits read from right to left correspond to increasingly higher powers of your base. For example, in base "n", tuvwxyz just corresponds to the number t*(n^6)+u*(n^5)+v*(n^4)+w*(n^3)+x*(n^2)+y*(n)+z The only problem is that you need n unique digits for the representation. Even using our alphabet, we only get 36 and that is still actually very unnatural to use. I only see really high order bases in mathematical proofs. I am not sure of any real application of them. ------------- "One had to be a Newton to notice that the moon is falling, when everyone sees that it doesn't fall. " |

Hey, this is a poll! You forget to vote! Sorry, I forgot to vote myself  . I pick 147, not because it’s more "progressive" but because it’s more unusual. And because 169 is in the lead right now.------------- He say nothing is quite what it seems; I say nothing is nothing (Peter Hammill) |

As far as I know they never used a 12, the Sumerians handed the system down to them when the Babylonians came into prominence. I'm not sure if eventually that was phased out for a base 12, but that seems unlikely. ------------- "One had to be a Newton to notice that the moon is falling, when everyone sees that it doesn't fall.
