Unit focus

  • An even number can be arranged into pairs with no remainder; an odd number leaves one unpaired. Parity follows predictable patterns under addition, subtraction and multiplication.
  • Use this routine: Pair the quantity → Identify parity → Test an operation → Generalise → Justify.
  • Watch for odd means prime: Many odd numbers are composite, such as 9 and 15.
