Do you want us to check your math ?

Lol, of course I just want you to check if I made any mistakes. I have found different answers on the internet of the same problem.
 
So, you can do the checking yourself. You have all you need to do it. The internet is notoriously unreliable. Note that PF is also on the internet :biggrin:
