I am working on a school project in which I have created a formula to calculate a score for the performance of a graphics card. It is as follows:

p= peformance

t=temperature

c=clock

I want to input this into excel and just use it as a shortcut instead of having to do: =(((K7*(10))+(G7*(10)))/2)+K7-(1150*(0.1)) :and re-inputting the columns every time. I'll have to use this for about 40 or 50 more excel documents, so any help would greatly be appreciated. ^_^
