But "term" is not a term that is restricted to computation. In normal mathematical usage, all values are always 'fully computed'. You may not personally know what they are, but that doesn't matter. These are just different names that we give to a single object.
replyTrue. But even in Mathematical Logic, a Term is a syntactical construct. You need to apply a "interpretation function" (mapping to a specific domain) to get a Value.
replyIn Computation this is just made explicit and clear using a "eval function".
