"It just doesn't hehe. No body can prove it. It's its own separate number, like 1 is different from 2."

Do you dare question this cutie pie math major on the first date?

I'd have more issue with using =\= over or !=

I mean, it's not a replacement for 1, it's just a mental exercise about rounding numbers.

It only exists because of rounding errors.

The funniest thing about .999... is it gets people to argue that 1/3 + 1/3 + 1/3 =/= 1.

0.99999~ isn't quite a real number, but "imaginary" number is already taken. It's closer to a "bullshit number", that only happens due to quirks of a basic mathematical operation.

It is a real number, and in fact it is an integer. It is just an alternative way to represent 1. It seems unintuitive because infinite series are inherently unintuitive.

I'd still say that 3(1/3) is the simpler and more intuitive way to explain the concept, because it also shows how you get there, and why it's just 1.

That's why you work through 3(1/3) instead of assuming some sort of "no, you're wrong!" authority.

Alright, let's try 3(1/3).

Divide 1 by 3. Multiply that by 3 again.
What did you get, and why would it not be 1?

Obviously she's going to fail her college courses if she thinks that and I'd have to support her, so I turn 360 degrees and walk away.

I contact her dean and recommend to them that they flunk her out of her degree.

There are no rounding errors in mathematics except in science fields with their use of significant figures due to limitations of the precision of their measurements.
