Difference between additive and multiplicative %

I have seen a few posts by GGG trying to clarify things by saying "NodeX" or "SkillX" is an additive % and "NodeY" or "SkillY" is a multiplicative %.

I want to make sure i understand.

if a stat is 40% (let's say resists) then an additive 10% = 50% and a multiplicative 10% = 44%?

Is additive listed a "increased by XX%"?

And is multiplicative listed as "XX% more"?

in American English those two mean exactly the same thing...not sure about Kiwi-speak.

2013 shows us the open beta for the world's largest guessing game.

As far as i'm concerned, there is pretty much no way of telling for this game, you just have to remember which one is additive and which one is multiplicative by trial and error.

Yeah thats what additive and multiplicative are. I wish they would say which node does what to the letter.

From what i remember of math additive would be + to the current number while multiplicative would be the number X n. But then again i barely passed math so feel free to fact check this for me. Hope i gave a new lead for you to find out which one is it as i am curious to know. :) Peace

as far as i understand it +x% is always multiplicative to the base amount and additive to other +x% increases from other sources unless otherwise stated.

as in (base = 100) * (1 + (0.1) + (0.3) ... + (n))
if that makes sense to you..

exception being resists and other things like regen and stuff that already start off as %'s (not chance to crit tho).

flat increases are always additive ofc. ;)

tbh i've never really had to guess much as to which was which as it seemed obvious to me...

if i hit 5 additive 4% nodes to a skill that is at 50% it would be 50% + (5*4%) = 70%, right?

if i hit 5 multiplicative nodes to a skill that is 50%*1.04^5 = 60.8%, right?

be more specific. which skill specifically are you talking about?

0.5 + (0.05 + 0.05 + 0.05 + ... + 0.05) would be additive,
0.5 * (1 + 0.05 + 0.05 + 0.05 + ... + 0.05) multiplicative.

edit: or rather 0.04 for the 4% in your example

There's two different multipliers.
Increased/Decreased and More/Less

If it's Increased, the multipliers are additive.
Meaning if you have 2 5% increase nodes. You get 10% total. So 50 * 1.1

If it's More. Then the multipliers are multiplicative.
2 5% MORE Nodes = 50 * 1.05 * 1.05

Where is Zakaluka when you need him :P
