Blown me away that one.

But surely it's there in black and white
maths is weird

Maths is perhaps the greatest conceptual achievement of the human race.....without it the Israelis might never have had a failed moon landing.....and I'd have had one less chuckle.

An interesting one, for sure..


"The reason some people think they are not equal is they say 0.999... is slightly smaller. The question to ask is "But how much smaller would it be?" You'd have to answer something like "It's '0.000...1' smaller" but there is no such thing. "An infinate amount of zeros... and then a 1." But there is no "after infinity", there is no such thing as infinismal numbers. And logically, if you can't find a number that is between two values, the two values must be the same number."

"Then what about 1.000... – 0.999...? You'll get an infinite string of zeroes. "But," you ask, "what about that '1' at the end?" Ah, but 0.999... is an infinite decimal; there is no "end", and thus there is no "1 at the end". The zeroes go on forever."

It's an explanation of semantics, I believe 0.999 is not 1.

It's maths semantics.

There’s a lot in maths which doesn’t make ‘sense’ at face value.

Get in to complex numbers - knowing there’s ‘imaginary’ numbers took me a while to get my head around.

It's 0.9 reoccurring, rather than 0.999.

"Then what about 1.000... – 0.999...? You'll get an infinite string of zeroes. "But," you ask, "what about that '1' at the end?" Ah, but 0.999... is an infinite decimal; there is no "end", and thus there is no "1 at the end. The zeros go on forever". This is why it works across numerous proofs.

Anyway cheers for the thread, Cryrst. Create a few more brain busters for us

My bank balance regularly attests to this!

It all comes down to whether you accept the existence of non-zero infinitesimals.

Personally I find the idea that two numbers can equal the same value as faulty.....if 0.9999 = 1 then get rid of one of them....I view it as semantics.

Maths uses symbols to represent how nature operates....It isn't a perfect representation of nature as we can't see the underlying 'code' as it were.

Still, if I'm wrong, I'm wrong.

It's just my take on it of course. While I enjoy and use a couple of areas of mathematics, I can certainly confirm that I'm not a mathematician by any means!
