• The addition of two complex numbers z₁ = a + ib and z₂ = c + id is defined as

z₁ + z₂ = (a + c) + i(b + d)
For example: (4 + 3i) + (−2 + 6i) = (4 − 2) + i(3 + 6) = 2 + 9i

• Several properties are exhibited by the addition of complex numbers.

• Closure law
  The addition of complex numbers satisfies closure property i.e., the sum of two complex numbers is a complex number.
  If z₁ and z₂ are any two complex numbers, then z₁ + z₂ is also a complex number.

• Commutative law
  The commutative law holds for the addition of complex numbers.
  If z₁ and z_2...
