Final answer:
The statement 'eight added by eight is sixteen' is categorized as C) For fact, as it is a verifiable mathematical operation that results in a factual sum according to arithmetic principles.
Step-by-step explanation:
The statement "eight added by eight is sixteen" can be evaluated based on its truth-value in the context of mathematics. In mathematics, when two numbers are added together, the result is a sum that is either correct or incorrect based on mathematical principles. Therefore, the statement falls into the realm of mathematical fact.
To determine the category of the statement, one must apply basic arithmetic. The process involves taking the number eight and adding another eight to it. The sum, which is sixteen, is a factual outcome of this operation, according to arithmetic, a branch of mathematics.
In context, the statement provided would be categorized as C) For fact. This is because the sum of the two numbers is based on objective and verifiable mathematical operation. The nature of mathematical truths is such that they are not dependent on personal beliefs or opinions, but rather on universally accepted axioms and rules that govern arithmetic.
The consideration of what makes something real, or whether there can be multiple realities, is a philosophical query. These questions delve into ontology and the nature of existence. When discussing mathematics, however, reality is confined to the consistent and repeatable outcomes that arithmetic provides, which is in stark contrast to make-believe, opinion, or non-fact.
