0.999... = 0.9 + 0.09 + 0.009 + ... = (9/10) + (9/100) + (9/1000) + ... = 9*(1/10 +1/100 + 1/1000 + ...) = -9 + 9*(1/10^0 + 1/10^1 + 1/10^2 + 1/10^3 + ...) (infinity) =-9 + 9 * ∑ (1/10)^n n = 0

Infinite geometric series formula: =9*(1/(1-(1/10))) - 9 =9*(1/(9/10)) - 9 =9*(10/9) - 9 = 10 - 9 = 1

I know it as 0=1

1+1+1+1+1+1+1+1......=1+1+1+1+1+1+1+1+1+1+1...... (1+1+1+1+1+1+1+1......)=(1+1+1+1+1+1+1+1+1+1+1......) (1+1+1+1+1+1+1+1......)=1+(1+1+1+1+1+1+1+1+1+1......) / -(1+1+1+1+1+1+1+1+)

0=1 0=1
