That's just simple mathematics; reduce the equation to its individual steps and you have the answer.

I never stop wondering: what kind of "engineers" are those somehow familiar with highly specialized and complex devices such as optical amplifiers but having problems with four elementary arithmetical operations? It looks like modern educational system is based on hoping for the miracle, allowing to skip "difficult" part and go straight to amazing results. It's also amazing that some student bye this lie...

It does not work like this here.

Here is what is expected of enquirers:
1. TRY first what you want to do! You may find that it's not that hard.
2. Formulate what was done by you that looks like an issue/not working.

Try them and tell if you face issues.
