Does 1 equal 2, you tell me? 😉 Here is the proof (unfiltered by rational arguments):

  • Let a and b be equal non-zero quantities
    a = b
  • Multiply through by a
    a2 = ab
  • Subtract b2
    a2b2 = abb2
  • Factor both sides
    (ab)(a + b) = b(ab)
  • Divide out (ab)
    a + b = b
  • Observing that a = b
    b + b = b
  • Combine like terms on the left
    2b = b
  • Divide by the non-zero b
    2 = 1
