That looks like the description of an EXPRESSION. However, an expression need not have "at least one operation"; a single number, or variable, is a perfectly valid expression.

Assuming you call your number "n", the expression would be "14n". You can replace "n" with whatever variable you want to use.

It is the coefficient of the variable

A variable expression has at least one variable in it (which is usually a letter that stands for an unknown number).

The term for replacing a variable with another value or expression is "substitution."

It is a poorly worded question. Any number in an expression can be a numerical variable.

Variable is any letter used in an algebraic expression, and can vary (change form) to be any number, and one variable means the same number in any single algebraic expression. Usually algebra is simplifying the expression or equation until you know what the variable is equal to.
