Imaginary and Complex Numbers

  • Imaginary numbers are the square roots of negative numbers.

  • All the properties of square roots extend to radicands containing complex numbers.

  • The complex numbers satisfy the commutative and associative properties for addition and multiplication.

  • To divide one complex number by another one, write the division as a fraction. Then multiply numerator and denominator of this fraction by the complex conjugate of the denominator.
