"Summation" already means something else, and funnily enough words can have different meanings in different contexts without causing any confusion.

OP literally emphasised the distinction between process and result in their post, specifically so that this exact confusion would not occur, and yet still everyone is talking about the word for the result instead of the process.
No. Everywhere uses the same terms, you just didn't understand the question.
The result of addition is the sum. The sum is calculated by summation of inputs.
The result of multiplication is the product. The product is calculated by __________ of inputs.
OP's question is: why can't the blank be "production", by analogy with "summation"?
