• This is pseudomathematics, not a reliable statement of logic founded on well-stated principles. It has no place here.
Does the simple sum 10/1 equal every answer possible. Follow:

10/1

1=a tenth(0.1)
10=ten times larger(100)

=100/0.1

=infinity/infinitely small.

• 10/1 is not a sum, it's a quotient.
• $\frac{10}{1} \neq \frac{100}{0.1}$
• $\frac{10}{1} \neq \frac{\infty}{ \infty^{-1} }$
Every claim you made was wrong. This is not an auspicious start. Why have you chosen to post here? Is there some specific reason?

Kinda reminds me of our previous... "pseudomathematician", Waiter_2001.

But one is a tenth of ten, hence 0.1

So then 10 is a hundred times larger than 0.1

So then 10/1 becomes

100/0.1

...and so on:

10*(10^infinity)/1/(10^infinity)

1 = 0.1 × 10
1 = 0.1 × 10 ⇒ 0.1 = 1 / 10
1 = 0.1 × 10 ⇒ { 10 = 10 AND 1 = 0.1 × 10 } ⇒ { 10 = 10 AND 1 = 10 × 0.1 } ⇒ 10 = 100 × 0.1

That does not follow.

What you have demonstrated was $x = ( 10 \, x ) \times 0.1$ which holds for all numbers x as well as all vector spaces over the rational numbers.

I agree.

One of things that's happening is that you are using ambiguous words with an indistinct mathematical meaning:
"hence", "becomes", "and so on"

In this example, you say the word, then freely interpret what it might mean mathematically:
So then 10/1 becomes 100/0.1

You know what you're trying to say, but it doesn't hold mathematically.

Infinity is 'nan'. 'not a number'

If you are trying to use infinity as if it were a number, that is a problem because it is the easiest method for producing inconsistent numerical results.

Okay. Thanks.
