You know how 1/3 = 0.33333......(repeating).

I can notate a repeating decimal for the purposes of this venue as 1/3 = .(3) .

Parentheses (x) denote x is repeated incessantly.

Now multiply both sides of the equation by 3:

3 times 1/3 = 3 times .(3)

ergo,

1 = .(9)

Or: One is zero point nine, nine, nine, nine, nine, repeated incessantly.

There have been TONS of debates across the internet with people trying to disprove this equation, 1 = .(9). They seem unequal, and the guess people make is that .(9) is less than 1.

Pages and pages of debate.

Next time we'll take a look at the Banach Tarski theorem which states that you can take a solid sphere of volume 1, cut it into 5 discrete pieces, and rearrange those pieces into two solid spheres of volume 1.
