What I understand that u want to code calculator and u asking about the equal_button
I think u just need to know which button has been clicked (to determine either to add or subtract or whatever ) , so declare Boolean variables lets say add and subtract ,at start both will be false ,

Dim add As Boolean
Dim subtract As Boolean

when add_button clicked make add =true and the other variables false
In equal button check which variable is true then do the calculation needed

hope this will help u
