## Working on a Tank Stat Spread Sheet...

I'm trying to figure out a formula to calculate the equivalent of adding 10 stam for armor.

In clearer words; I took my current stats, then added 10 stam to find out the increase in effective health. I'm trying to find out the equivalent effective health addition by adding armor through a formula.

Example numbers:

Current Stats:
Health - 21256
Armor - 15651
Arm % - .5972
Eff Health - 52767

21382
Effective Health - 53080

In order to match that upgrade you need .5995 armor reduction.

So I'm trying to find a way to isolate the armor value using the armor reduction formula;

Armor/(armor+10557.5)=Damage Reduction

A/(A+B)=C

And for some God forsaken reason I can't remember/figure out how to isolate the A. Been too long since Algebra 1.

Any help?

2. A/(A+B)=C
A=C(A+B)
A=AC+BC
A-AC=BC

A=?
B=10557.5
C=.5995

A-A*.5995=10557.5*.5995
.4005A=6329.2
A=15803.3

152 Armor increase

Works =P

Completely forgot to go back to the coeffs when trying to figure out the isolation.
