Sum of two complex number is given by :

(a+bi)+(c+di)=(a+c)+(b+d)i

From the equation, the real parts of the complex equations get summed up and the imaginary parts are summed up separately.

How to use the IMREAL function in Excel?

Using this function in a WS is simple; all you need to do is enter the function as a formula of the cell in the formula bar.

Take a look at the given example

To find out the real coefficient of the complex numbers, Enter the complex numbers in columns A, B, C and enter the following formula in Column D,

Formula: =IMSUM (A1,B1,C1)

Here, A1 refers to the cell name or the cell address. Repeat the same to the other cells and you will get the sum of the complex numbers
