How would these damage resists stack?

[King ECHatron II]

I'm currently using Vexcalibur on Strand and Synthoceps for this entire season/episode.

I think the damage resist for glaiveshield is 90%, correct me if I'm wrong
Void Overshield is 50% with 100 health if I recall correctly
Woven Mail is 30% resist, again...if my mind serves me right
What if I also use a gun with Rimestealer and stack Frost Armor?

My dumbass doesn't know how DMG resist stacking works in Destiny 2, even though I got ALOT of hours on this game. can anyone help me out with how to calculate this?
