In order:

  • 4 − 2 × 2 − 3 = 4 − 4 − 3 = − 3 4 - 2 \times 2 - 3 = 4 - 4 - 3 = -3 Order of operations: the multiplication is done first.
  • 0 + − 1 = − 1 0 + -1 = -1
  • 1 1 is not prime. The definition of prime explicitly excludes 1.
  • e π i = − 1 e^{\pi i} = -1
  • i 396 = 1 i^{396} = 1

When I (i) multiply myself 396 396 times (or any multiple of 4 4 times) , I am the ONE ( 1 1 ) and ONE only.
