The Excel IMPRODUCT function returns the product of one or more complex numbers. The complex number must be in the form x + yi or x + yj. Use the COMPLEX function to create a complex number from real and imaginary parts

**Syntax**:= IMPRODUCT(inumber1, [inumber2], …)

The IMPRODUCT function syntax has the following arguments:

**Inumber1, [inumber2], …**Inumber1 is required, subsequent inumbers are not. 1 to 255 complex numbers to multiply

**Example**: Let’s look at some Excel IMPRODUCT function examples and explore how to use the IMPRODUCT function as a worksheet function in Microsoft Excel:

**Syntax**: =IMPRODUCT(A2,B2)

**Result**:

Based on the Excel spreadsheet above, the following IMPRODUCT examples would return:

**Syntax**: =IMPRODUCT(A3,B3)**Result**: 12-4i

**Syntax**: =IMPRODUCT(A4,B4)**Result**: 90+120i

**Syntax**: =IMPRODUCT(A5,B5)**Result**: -17-51i

**Syntax**: =IMPRODUCT(A6,B6)**Result**: -11+18i

**Syntax**: =IMPRODUCT(A7,B7)**Result**: -16-37i

**Syntax**: =IMPRODUCT(A8,B8)**Result**: 1+9i

**Syntax**: =IMPRODUCT(A9,B9)**Result**: 8+10i

**Syntax**: =IMPRODUCT(A10,B10)**Result**: 54-99i

**Syntax**: =IMPRODUCT(A11,B11,C11)**Result**: 411-378i

**Syntax**: =IMPRODUCT(A12,B12,C12)**Result**: 75+125j

**Syntax**: =IMPRODUCT(A13,B13,C13)**Result**: -4-58j

**Note**:

- The formula returns the #NUM! error if the complex number doesn’t have lower case
**i**or**j**(iota). - The formula returns the #VALUE! Error if the complex number doesn’t have correct complex number format.
- The product of two complex numbers is:
