make 1 =.999...

This argument is realyla bout semantics.

Math as a written language is a tool describe what's happening. It is by no means perfectly capable of representing the many nuances that exist.

like, the number .9999.... does not change over time. It remains the same number all the time, and it is not dependent on the number of 9's you write, because the ... symbol means that there are an infinite number of 9's, and infinity is not a number that changes, it is a concept that is the same all the time, and does not vary at all. you seem to think that the number somehow "changes" over time, as if someone has to sit there and keep writing 9's forever until the number becomes what it is. that simply is not how things work, and the number just is 1 right away, and doesn't have to sit there and wait for its value to increase slowly over time.
But there is a difference. The difference is .000...1

from wiki: "The equality 0.999... = 1 has long been accepted by mathematicians and is part of general mathematical education. Nonetheless, some students find it sufficiently counterintuitive that they question or reject it, commonly enough that the difficulty of convincing them of the validity of this identity has been the subject of several studies in mathematics education."

You just linked to a video proving that .9999... =1
Unless you miss-worded your first sentence. :P

How do you determine if two numbers are equal?

Iirc: x = y if and only if x - y = 0

If 0.9... - 1 = 0, then they are equal and vice versa.
Besides, the sum of the infinite series 9/(1-r) where r = 0.1 IS 1. Not about. Not increasing closer to one. It IS one. And that's all 0.9... is. An infinite series.

Multiply it by 3.

1=.99999 repeating

GG GD
or stop bring silly and do it like this :

1/3 x 3 = 1

or

1/3 = 0.333333..... indefinitely

3x0.3333333...... = 0.9999999.....
0.999999.... = 1

quit being dishonest or just stupid

.000...1 is not a number. Your "difference" literally does not exist.

If someone has 100 health, and you auto them for 99.9999999999999999~ damage, do they live or die?
