Deductions & credits

I have this same question. The page linked says that:

 

"If your tax home is in the United States, and you are temporarily in a foreign country away from your tax home in the USA for less than 1 year, then you may be able to deduct your airfare, local transportation, lodging, and food expense as itemized deductions reported on Form 2106, Employee Business Expenses (or Form 2106-EZ) and Schedule A of Form 1040.

 

But how do I calculate how much I can exclude? And "exclude" is weird, right? Doesn't it mean deduct?

 

Can I use the M&I value from the state department? Even if I had family with me, I'm the only qualifying individual, right? Can I use the Lodging figure instead of including the cost of my rent?


Thanks to anyone that can help clarify this!
