Identity Property

Identity Property of Rational Numbers: Some important properties that should be remembered are:

Additive identity: Zero is the additive identity for Rational, natural, whole numbers and integers, since adding it to them does not change the result.

  • 13 + 0 = 13
  • large frac{-5}{6} + 0 = large frac{-5}{6}
  • Hence, 0 + a = a + 0 = a, where a can be rational number or natural number or whole number or integer.

    Multiplicative identity: One is the additive identity for Rational, natural, whole numbers and integers, since multiplying it to them does not change the result.

  • 3 x 1 = 3
  • large frac{-4}{7} x 1 = large frac{-4}{7}
  • Hence, 1x a = ax1 = a, where a can be rational number or natural number or whole number of integer.
