Why 0.999... Equals 1: A Simple Explanation That Makes It Click
I used to find it strange that 0.999... equals 1, until I looked at it from a different angle. If you set x = 0.999..., then 10x = 9.999... — subtracting the two gives 9x = 9, so x = 1. It’s all about how infinite decimals behave in real numbers. This helped me appreciate how math handles limits and infinite processes. Has anyone here found a different explanation that really helped the concept click?
