You can't divide a/b if b is zero. The step where he cancels out the 10 - 10 over 10 - 10 is not feasible.

 

[Integral]

That is proof that if you start with nonsense you can prove most anything. Which of course is nonsense.

The step where he cancels out the 10 - 10 over 10 - 10 is not feasible.

Amusingly enough, this step assumes 0/0=1 in order to proceed and then 'prove' 0/0=2 :)
