Additive vs Multiplicative Modifiers

I will attempt to explain why I will be swapping the descriptions of additive and multiplicative damage modifiers. Both additive and multiplicative modifiers are eventually applied to the value they affect through multiplication—that does not change and is obviously not the fact from which their names are derived. The difference between them lies in how values of each type are applied to modifiers of the same type. Multiplicative modifiers have a multiplicand-multiplier relationship with other multiplicative modifiers. Additive modifiers have an augend-addend relationship with other additive multipliers.

To illustrate, let "mn" be the "n"th multiplicative modifier and "an" be the "n"th additive modifier (assuming all modifiers are in the appropriate form i.e. 1.2 for a 20% modifier). Then:

result = valueToBeModified * m1 * m2 * m3 * ... * mn * (a1 + a2 + a3 + ... + an)
