Look up Additive in Wiktionary, the free dictionary
When used as a noun, additive refers to something that is introduced to a larger quantity of something else, usually to alter characteristics of the larger quantity. For example, sweetener is used as an additive to alter the flavor of food.
When used as an adjective, additive means that things can logically be added together. For example, when determining the number of apples, an orange is not considered additive. If the operation of addition is replaced by multiplication, the corresponding adjective becomes multiplicative.
An alternative to additive is fungible. A product is fungible if the quantities of the product can be added together to get a new quantity. One instance of a product is as good as any other instance of the product. Money is a good example of a fungible product. An example of a product that is not fungible would be a contract. If I have two contracts with you, I canot merge them into one contract without agreement.

Additive Color Synthesis is the method of creating color by mixing various proportions of two or three distinct stimulus colors of light.
The distinguishing features of additive color synthesis are that it deals with the color effects of light rather than with pigments, dyes, or filters, and that the stimuli come from separate monochromatic sources.
The most common example of additive color synthesis is the color television screen, (or RGB monitor), which is a mosaic of red, green, and blue phosphor dots; at normal viewing distances the eye does not distinguish the dots, but blends or adds their stimulus effects to obtain a composite color effect.
Additive synthesis emulates such timbres by combining numerous waveforms pitched to different harmonics, with a different amplitude envelope on each, along with inharmonic artefacts.
Additive synthesis can also create non-harmonic sounds if the individual partials are not all having a frequency that is an integer multiple of the same fundamental frequency.
It has been shown in Wavetable Synthesis 101, A Fundamental Perspective, that wavetable synthesis is equivalent to additive synthesis in the case that all partials or overtones are harmonic (that is all overtones are at frequencies that are an integer multiple of a fundamental frequency of the tone as shown in the equation above).
