  Is this too vague?

  I can only think that it's:

  1 % 9 % 8 = 1 2 % 8 % 9 = 2

  Interesting idea. There's a way to get the answer to 2+8+9 without using mod though.

  if the addition operator is substituted for the exponent operator then 1⁹⁸ = 1

  That means 2⁸⁹ is about 1.2 x 10^40000000 (assuming ^ is right associative)

  • 1 = One
  • 9 = Nine
  • 8 = Eight

  ONE

  • 2 = Two
  • 8 = Eight
  • 9 = Nine

  TEN

  Why is TEN the answer? I don't see the pattern.
