Isn't it the other way round?

-- giving an example to demonstrate the function --

You're just back from your last shopping trip to the Adventurer's Mart and on your way to the government district to visit your good friend Sir Keldorn, when you are waylayed by Faceman a delusional lvl 10 Necromancer who just escaped from Spellhold. The madman casts Greater Malison at you followed by Polymorph other.
You are wearing a Ring of Protection +1 and your saving throw vs Polymorph is 7.
How likely is it that you'll become a squirrel in the next seconds?
Let's break this down.
Whatever you roll (1-20) will have to match or beat your saving throw (7) after the penalties and bonuses have been added/subtracted.
So
x - 4(GreaterMal) + 1 (RingoP) > or = 7 would make you stay human (suppose you were human before).
If you roll a 14 for example this breaks down to
14 - 4 + 1 = 11 As 11>7 you stay human
Had you rolled 9 ...
9 - 4 + 1 = 6 you'd be exchanging breathcare tips with Boo right now.
To calculate what you have to roll at least to succeed just take the left side to the right
x = 7 + 4 - 1 = 10


Rather long but I hope it clarifies things more than mixing them up

EDIT just typos
