It's quite simple once you get the idea of it. Here, let me use 2 things that are no longer in the game to explain it to you, since it's easier (sorry):

-Deathfire Grasp "DFG"

-Ahri's Charm (pre-5.2)

Both of these things made it so that a target would take 20% more magic damage. So, if we only take one, say DFG, the total damage would be 120% of what it is normally. However, if we add another multiplier in, say Charm, then the 20% bonus damage from Charm would also affect the 20% bonus damage from DFG, causing a total of 44% more damage, or 144% total.

If that's a little confusing, here's just plain math:

100 x 20 = 20 % bonus damage from item/spell 1

100 + 20 = 120 % total damage

120 x 20 = 24 % bonus damage from item/spell 2

20 + 24 = 44 % bonus damage in total

100 + 44 = 144 % total damage, combining both items/spells

Normally-100% damage

With DFG-120% damage

With DFG and Charm-144% damage
