R<​sub>​n​ are equal but not equal to R<​sub>​f​ then from the equation we can see that it can be simplified such that the output will be equal to the algebraic sum of the inputs times a common gain factor of -R<​sub>​f/​R<​sub>​1​. If all the resistors are made equal including R<​sub>​f​ then the output will be simply the negative sum of the inputs. If all the input resistors R<​sub>​1,​ R<​sub>​2,​ ...
