Maths proves 1=0.999.. thus ends in self contradiction

[Chas]

This work points out that mathematics ends in meaninglessness for 4 reasons
[SNIP]
1) maths proves s 1=0.999.. ie a finite number= a non-finite number thus a contradiction in terms thus maths ends in self contradiction
2) 1+1=1
3 ZFC ie axiomatic set theory is inconsistent
4) mathematics cant tell us what a number is without circularity-thus mathematics is meaningless

Your ignorance is showing, Google "infinite series".
