If you by "=" mean "equal to" by standard base ten arithmetics I wold say that this postulate is false.*Originally posted by sonhouse***I hope you didn't read a certain recent thread where I figured it out!**

If you by "200" mean "5 halfves" then all make perfectly sense (!)

If you by "5" mean "four hundred" then all make perfectly sense (!)

If you by "+" mean any operation that make 200+200=500 then all make perfectly sense (!)

In any other case 200+200 is not = 5. (?)- Joined

Good, that makes it a real puzzle for you,

So its two hundred plus two hundred equals 5 in base ten. Its a regular addition and the = sign is a normal run of the mill equal sign and the 5 is a standard issue base ten 1 2 3 4 5 kind of integer.

So whats going on?- Joined

Oh, but I did!*Originally posted by sonhouse***AH, clearly you did not read the recent thread where I figured it out.**

I wrote "in standard base ten arithmetics", didn't I?

That means exactly as it says.

If 200+200=5 - then it isn't in any standard base ten arithmetics, how could it?

Well, semi-solid math anyway! Its a real representation, mathematically correct.*Originally posted by FabianFnas***Oh, but I did!**

Well, then I have to wait for the solution.*Originally posted by sonhouse***Well, semi-solid math anyway! Its a real representation, mathematically correct.**

I asked my math professor: "What is 200 + 200, professor?" And he said "If you don't know that, you have to start from the low grade beginning again. Approximatly 400, of course!" Approx? Yes, he teaches numerical methods...

My local banker probably believs it, I think.

"If I save 200 Euro one month and saves 200 Euro next months, how much money do I have in my accont thereafter?"

And of course in base ten your professor is correct. OOPS I just threw in a big hint.ðŸ™‚- Joined

The smallest base you can use a symbol "5" in is base 6.*Originally posted by sonhouse***And of course in base ten your professor is correct. OOPS I just threw in a big hint.ðŸ™‚**

200 in base 6 is 72 in base 10. 72+72 in base 10 is 144 in base 10 which is in base 6 ... far more than 5 anyway. And in higher bases the difference is even more.

Are we talking base or modulus? I think you are using modulus arithmetics, am I right?- Joined

Its not modulus, its a base thing. You have to make one mental jump though.*Originally posted by FabianFnas***The smallest base you can use a symbol "5" in is base 6.**

I wrote "in standard base ten arithmetics", didn't I?*Originally posted by sonhouse***Ok, here is a hint: base systems don't have to use integers.**

That means the decimal base system, not binary, not octally, not hexadecimally, but decimally with the base of ten.

I know of course that A hexadecimally means 10 decimally, no funny with that. In binary 1 + 1 = 10 but now we are talking of base ten arithmetics, didn't we?

So if 200+200=5, then it is not plain old fashion base ten arithemtics we're talking about...? And that is exactly what I've said from the beginning.

rushing to and fro11 Apr '06 21:432 editsDoes 200 = 200 or are these in different bases as well? It would seems that there might be multiple "correct" answers.

EDIT: If 200 = 200, then 200 = 2.5,

or 100 = 1.25 or 5/4, so it would seem that the base is (5/4)^0.5

This would be an odd counting system, however, as:

100 = 1.25

200 = 2.5

1000 = ~1.4

200 > 1000 ???

Or perhaps my math is wrong.... ðŸ˜ž It's been about 10,000,000,000,000,000,000,000 years since I took any math classes! ðŸ˜µ
