International Asset Pricing - Help!

I am having extremly hard time understanding the basis of how to solve problems in International asset pricing.

Totally get confused by nominal rate, real rate, appreciation/deprecitaion, inflation rate difference , risk free rate differences.

I worked on a few examples in Swechzer but i just CANT UNDERSTAND THE LOGIC behind…

Please help me quickly summarize how to calculate domestic return, foreign return.

Really appreciate your help on this.
