We will examine changes in the argument of a complex number using the four basic arithmetic operations on two complex numbers, a and b.
The unit of argument is degrees.
Let c be the complex number resulting from the arithmetic operations.
Here, the change in argument refers to the increase or decrease in the argument when a’s argument changes to c’s argument as a result of the arithmetic operations.
(Increase or decrease = c’s argument – a’s argument)
a
  (Enter within the range of complex numbers)
b
  (Enter within the range of complex numbers)
The argument of a 
b's declination 
The numerical value of c = a + b 
The argument of c Changes in Declination 
The numerical value of c = a - b 
The argument of c Changes in Declination 
The numerical value of c = a * b 
The argument of c Changes in Declination 
The numerical value of c = a/b   (When b is not 0)
The argument of c Changes in Declination 
+ is addition.
- is subtraction.
* is multiplication.
/ is division.
When b=0, division is not performed.
