Additivity
Definition
The property of certain quantities, functions, or systems to have a global value equal to the arithmetic sum of their individual component values. In a structural and mathematical sense, this phenomenon defines linear operators and extensive physical quantities (such as mass, volume, or energy), where the total effect of an assembly is obtained by the simple direct summation of partial effects, without distracting secondary interactions.
