Solution 2

Try operator overloading like this

Public Class Form1

Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
Dim a, b, c As New COmplexNumber
a.realNum = 1
a.imaginary = 2
b.realNum = 2
b.imaginary = 3

c = a + b

TextBox1.Text = c.realNum & "+i" & c.imaginary
End Sub

End Class
Public Class COmplexNumber
Public realNum As Integer
Public imaginary As Integer

Public Shared Operator +(num1 As COmplexNumber, num2 As COmplexNumber) As COmplexNumber
Dim result As New COmplexNumber
result.realNum = num1.realNum + num2.realNum
result.imaginary = num1.imaginary + num2.imaginary
Return result
End Operator

End Class

try this code i hope it will work

SQL

Public Class COmplexNumber
    Public realNo As Integer
    Public imag As Integer


  Public Function calctn(C1 As COmplexNumber, C2 As COmplexNumber,ByVal optr as string) As COmplexNumber
        Dim result As New COmplexNumber
        if (optr ="+") then
        result.realNo = (C1.realNo + C2.realNo)
            result.imag = (C1.imag + C2.imag)

    else if (optr ="-") then
        result.realNo = (C1.realNo - C2.realNo)
            result.imag = (C1.imag - C2.imag)

    else if (optr ="*") then
        result.realNo = (C1.realNo * C2.realNo)
            result.imag = (C1.imag * C2.imag)

    else if (optr ="/") then
        result.realNo = (C1.realNo / C2.realNo)
            result.imag = (C1.imag / C2.imag)
    end if
        calctn = result
    End Function
End Class
