Engineering Beginner LibreOffice Calc

An explanation of LibreOffice Calc IMPRODUCT, including tested formulas, examples, expected results and common mistakes.

Tested: Examples checked in LibreOffice Calc 25.2.3.2. What this means

Returns the product of several complex numbers. The result −5+10i follows from (1+2i)(3+4i) and the identity i²=−1.

Syntax and arguments

=IMPRODUCT(Complex_number; Complex_number)

LibreOffice Calc formulas generally separate arguments with semicolons (;).

Argument Explanation
Complex number The first complex number
Complex number Another complex number (optional)

Worked examples

Example 1: Multiply two complex values

=IMPRODUCT("1+2i";"3+4i")

Expected result: -5+10i. This value was returned in the LibreOffice Calc 25.2 test.

How to interpret the result

The result −5+10i follows from (1+2i)(3+4i) and the identity i²=−1.

Mistakes and troubleshooting

  • Check inputs and assumptions: Multiply both real and imaginary parts; you cannot multiply components independently.
  • Check argument order and format: Strings go in quotes, cell references do not. Functions that return arrays may require special entry.
  • Verify your own data: Reproduce the example first. If your formula returns an error, inspect the referenced cells and individual argument values.
