(In reply to re: solution is wrong by Tristan)

infinity never ends yes but if u infinity-1, then that has an end meaning it is finite


In addition, theoretically, 3.99999... needs a 0.000...1 to equal 4. this might be slightly flawed coz 9's go on forever and the 0.000...1 has an end, but still, i dont see how one number can equal another one. its like the 2 = 1 proof
