"Calculation Rules" are simply the rules that get attached to cubes, and may cover calculations like currency conversion, referencing data from other cubes, calculating percentages etc.
"Drill Through" or "Drill Down" rules are used in combination with Drill Through processes to create associations between cubes, that allow you to for example access more detailed information from a summary cube.
