Question

are national number between -2/3 and 1/2 is​

Answer 1

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

3 + 0 = 3

-4/5 + 0 = -4/5

Hence, 0 + a = a + 0 = a, where a can be rational number or natural number or whole number of 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
