### Does this even make sense?

"School conditions you to reject your own judgement and experiences. The facts are in the textbook. Memorize and follow the rules. What they don't tell you is the people that discovered the facts and wrote the textbooks are people like you and me."

### Re: Does this even make sense?

Yes, it does. There is another proof that 0.999... = 1

Let x = 0.999... [Equation 1]
Or, 10x = 9. 999.... [Equation 2]

Subtracting [Equation 2] - [Equation 1]:
9x = 9.000
Or, x = 1

### Re: Does this even make sense?

It makes sense but a simpler version of of it is:

1/3 = 0.3333.....
3/3 = 1
3*0.33333 = 0.99999.....
3*1/3 = 1
o.9999.... = 1
