comment Can Prime numbers be negative?
Please define what you mean by "generic." Also what does "So, of the integers, 7 represents both 7 and -7." mean?

comment Can Prime numbers be negative?
It is the numeral $7$ that represents a particular number, while the numeral $-7$ represents the opposite or additive inverse of $7$.

comment Is this a misuse of the word “evaluate”?
The last question in this "fifth-graders" introduction to continued fractions asks: "By trying several examples, discover and describe the relationship between the continued-fraction forms of a fraction and its reciprocal." At this point I don't think I'm smarter than a fifth-grader.

In my opinion, those fifth-graders have the right to scream "CONTRADICTION!!!" after being preached the sentence: A variable expression is evaluated by replacing each variable with a given value and simplifying the resulting numerical expression. (NOTE: this is a joke.)

Thank you for the examples, but wouldn't simplify or convert make more sense?

@DustanLevenstein these are the classic Algebra textbook definitions. A numerical expression, or numeral is an expression that names a particular number.

@DustanLevenstein Replacing a numerical expression by the simplest name for its value is called simplifying the expression. Replacing each variable in a variable expression by a given value and simplifying the result is called evaluating the expression.

@DustanLevenstein Have we not also been trained to simplify an expression involving fractions, you write it as a single fraction in simplest form?

average: The average of a set of numbers is the sum of the numbers divided by the number of numbers.
