Is it possible to do math with a path?

I will use three buttons as an example This script is very rough but I want to know if It's possible to do math with path values of some sort.

I am trying to use paths instead of numbers.

PathA = PathA + PathB
PathA = PathA - PathB
PathA = PathA * PathB
PathA = PathA / PathB
PathA = PathA <=PathB

Note: I am not trying to fix a script I want to know if this method is possible and if it will work correctly.

I know the script does not work.

--Rough Example

local ButtonHolder = script.Parent
local pathA = ButtonHolder.ButtonAHolder.ButtonA
local pathB = ButtonHolder.ButtonBHolder.ButtonB
local PathNameA = ButtonHolder.ButtonAHolder
local PathNameB = ButtonHolder.ButtonBHolder

local Subtract = ButtonHolder.Subtract


Subtract.MouseButton1Down function()) 
pathA.Value = PathA.Value - PathB.Value  --Subtracting a path value

end)
