As I understand it:

• if you have Advantage from two different sources, you simply have Advantage (no stacking)
• if you have advantage from one source, and disadvantage from one source, they cancel out.

So what if you have advantage from two or more sources, and disadvantage from one source? My assumption is that you simply have advantage, or put another way, you have Advantage on a roll when the # of Advantages > # of Disadvantages (and vice versa).

Is that correct?
