The proof of the inconsistency of aritmetics is a pseudomathematical proof used by some creationists to prove that 0=1 as a means to prove that something can exist out of nothing. According to believers of this theory it is fundamental to believe in it because it is a proof that a creator exists. The actual inventor of this proof is Luigi Guido Grandi and was developed by him in 1703. [1].


The proof can be explained in 4 steps:

  1.  0=0+0+0+0+ \ldots
  2.  0=(1-1)+(1-1)+(1-1)+(1-1)+ \ldots
  3.  0=1+(-1+1)+(-1+1)+(-1+1)+ \ldots
  4.  0=1 ~ \blacksquare

Problem of the proof[edit]

At step one it is assumed that zero can be written as an infinitely converging row of values. In aritmetics, such a thing is extremely problematic as you can not know the outcome of infinity multiplied by zero at face value.

Extra notes[edit]

The series at step 2 has been named as Grandi's seriesWikipedia's W.svg in his honor. Though Niels Henrik Abel [2] would have probably thought of him as a Satan worshipper.
