Additive processes add stuff to the original piece. Think welding or adhesive bonding. Subtractive would be maybe a machining process that takes material away. Trailing zeros mean greater tolerance is required and that comes at a higher price.
no 1 is not an additive identity
The additive inverse for a number is its negative value. The sum of an integer and its additive inverse is zero. For the example (5), the additive inverse would be (-5).
Printing is a subtractive process; all the colors combine to form black.
The additive color process is mixing lights while the subtractive color process is mixing paints and dyes. In the additive color process when you mix all of the main colors together: red, green, and blue: you get white(hence the name additive) while if you do the exact same thing in the subtractive color process: cyan, magenta, and yellow: you get black(hence the name subtractive because in order to get white you'd have to take away all of the colors).

Carving
carving
Additive processes involve adding material to the piece. Subtractive processes involve taking material from the piece. Painting is additive because you add paint. Carving is subtractive because you take away pieces from your original block.

subtractive sculpture ( . Y . )
Subtractive - because they remove material from the object being ground.
In subtractive processes, the sculptor begins with a mass of material larger than the finished work and removes material, or subtracts from that mass until the work achieves its finished form. Carving is a subtractive process. In additive processes, the sculptor builds the work, adding material as the work proceeds. Modeling, construction, and assemblage are additive processes.
