MATHEMATICAL PROBLEM....PLEEEZ SEE DIS FAULT...


 


s =1+2+4+8+.....


   = 1+ 2(1+2+4+8.....)


   = 1+2s


so.,,,


s =1+2s


hence s = -1




...how come 1+2+4+8+.....=-1   ???


positive nos. added to b negative???

Which fault??????

God does not care about our mathematical difficulties. He integrates empirically. ~~~Albert Einstein (1879-1955)~~~~
To divide a cube into two other cubes, a fourth power or in general any power whatever into two powers of the same denomination above the second is impossible, and I have assuredly found an admirable proof of this, but the margin is too narrow to contain it.~~~Pierre de Fermat (1601-1665)~~~

s=1+2+4+8......

is wrong since the sum itself diverges you can't assign any real number to it
