# How to Use IMPRODUCT in Google Sheets in 2020?

IMPRODUCTReturns the result of multiplying a series of complex numbers together.

Sample Usage

IMPRODUCT(A2:A100)

IMPRODUCT(“1+2i”,3,”4i”)

IMPRODUCT(“1+2i”,”3+5i”,A2:A50)

Syntax

IMPRODUCT(factor1, [factor2, …])

factor1 – The first complex number or range to calculate for the product.
factor2, … – [ OPTIONAL ] – More complex numbers to multiply by.

Notes

The product of two complex numbers is defined as follows:

You can multiply complex numbers only if they have the same suffix (i or j). For example, you can’t do IMPRODUCT(“4+3i”, “1+2j”).

COMPLEX: The COMPLEX function creates a complex number, given real and imaginary coefficients.
IMREAL: Returns the real coefficient of a complex number.
IMAGINARY: Returns the imaginary coefficient of a complex number.
IMDIV: Returns one complex number divided by another.
IMSUM: Returns the sum of a series of complex numbers or cells or both.
