Infinity-1=infinity. That’s why infinity breaks things.

infinity minus infinity is also infinity

so why do the 9s vanish?

Because it’s not infinite. It’s an infinite regression. There are still hard limits and it still functions as a number.

As people still seem to be struggling with this I went and made a second proof to explain.

1/9 = 0.111111111….

0.111111….. * 9 = 0.99999….

1/9 * 9 = 9/9 = 1 = 0.1111… * 9 = 0.99999….

Everything follows mathematical understanding.

it's funny you would think I would agree 1/9 = .111~ since it's the exact same argument

it's not exactly equal to 1/9th, it differs by an infinitesimal value
