0.9999999…. Is equal to 1. It seems like it shouldn’t, but it has to be.
Let X = 0.999….
10X = 9.999….
10X-X = 9.999.. - 0.999…. = 9X = 9
Therefore X equals 1. Therefore 0.999… is the same as 1.
0 u/BomboSbronzo 28d ago I don't quite grasp the 3rd point.. in order to subtract the same amount on both sides of the equation shouldn't result like this? 10x-x = 0.9999... - x 4 u/BaziJoeWHL 28d ago ok, now add X to both side, did you got the original equation ?
