What is Complex Number?

A Complex Number is expressed in the form of a + bi where a, b are real numbers and i is the imaginary part. In the given expression a is the real part and b is the imaginary part of the complex number. Complex Number extends the concept of one-dimensional line to a two-dimensional complex plane and uses the horizontal axis for the real part and vertical axis for the imaginary part.

How to Multiply Complex Numbers?

We know the expansion (a+b)(c+d)=ac+ad+bc+bd

Similarly, consider the complex numbers z1 = a1+ib1 and z2 = a2+ib2

Product of z1z2 is defined as

z1z2 = (a1+ib1)(a2+ib2)


we know the value of i2 is -1


For any non-zero complex number z=a+ib(a≠0 and b≠0) there exists another complex number z-1 or 1/z which is known as the multiplicative inverse of z such that zz-1=1 has got concepts like perimeter, area, volume, trigonometric functions, algebra, percentages, and many more along with their relevant calculators all one under one roof.

FAQs on Multiplication of Complex Numbers

1. What is the Product of two Complex Numbers?

The Product of two Complex Numbers is also a Complex Number.

2. What happens if you multiply a complex number with its conjugate?

If you multiply a complex number with its conjugate the answer is always a real number.

3. How do you multiply Complex Numbers on a Calculator?

You just need to give the input values i.e. complex numbers and tap on the enter button to get the product of numbers.

4. What is the Product or Multiplication of Complex Numbers (2+2i) and (4+4i)?

Given Complex Numbers are (2+2i) and (4+4i)

As per the formula


Multiply as per the formula

Product = (2+2i)*(4+4i)


= 8+8i+8i+8i2

we know the value of i2 = -1

= 8+16i+8(-1)


= 16i

Therefore, the product of Complex Numbers (2+2i) and (4+4i) is 16i
