The IMPRODUCT function calculates the product of complex numbers in x + yi or x + yj text format.

The letter j is used in electrical engineering to distinguish between the imaginary value and the electric current.

A product of two complex numbers is calculated like this:

C_{1} = x + yi

C_{2} = z + wi

IMPRODUCT(C_{1},C_{2}) = (x+y)(z+w) = (xz - yw) + (xw + yz)i

## 3. IMPRODUCT function example

The image above demonstrates a formula in cell D3 that calculates the product of two complex numbers specified in cells C3 and B3.

Formula in cell C3:

=IMPRODUCT(B3, C3)

### 3.1 Explaining formula

#### Step 1 - Populate arguments

IMPRODUCT(*inumber, number*)

becomes

IMPRODUCT(B3, C3)

#### Step 2 - Evaluate the IMPRODUCT function

IMPRODUCT(B3, C3)

becomes

IMPRODUCT("1+2i", "-1-2i")

and returns

3-4i
