IMSUB

Returns the difference between two complex numbers.

Sample Usage

IMSUB("6+5i", "2+3i")

Syntax

IMSUB(first_number, second_number)

• first_number - The complex number to subtract second_number from.
• second_number - The complex number to subtract from first_number .

Notes

• The difference between two complex numbers is defined as follows:
  • (a+bi) - (c+di) = (a-c) + (b-d)i
• You can subtract two complex numbers only if they have the same suffix (i or j). For example, you can't do IMSUB("4+3i", "1+2j") .
