I stubled across 3 false proofs, see if you can find the errors.

#1

  • X=Y
  • X^2=X*Y
  • X^2-Y^2=X*Y-Y^2
  • (X+Y)*(X-Y)=Y*(X-Y)
  • X+Y=Y
  • 2Y=Y
  • 2=1

#2

  • X=0.99999...
  • 10X=9.99999...
  • 10X-X=9.99999...-X
  • 9X=9
  • X=1
  • 0.99999...=1

#3

This one is a word problem. Imagine a square with sides of 4, and therefore a perimiter of 16. Cut corners, and the perimiter stays the same. See below for a visual.


  • HHHHHHHHHH
  • HHHHHHHHHH
  • HHHHHHHHHH
  • HHHHHHHHHH
  • HHHHHHHHHH
  • HHHHHHHHHH


The perimeter of the above shape is equal to the perimeter of the shape below. (_ equals negative space)

  • ____HHHH____
  • ____HHHH____
  • HHHHHHHHHH
  • HHHHHHHHHH
  • ____HHHH____
  • ____HHHH____

Repeat to infinity. Square becomes a circle

  • 16=Pi*(2)^2

Therefore, Pi equals 4


That's all folks!
