Answer:
"Evaluation" mostly means "simplifying an expression down to a single numerical value". Sometimes you will be given a numerical expression, where all you have to do is simplify; that is more of an order-of-operations kind of question
example: So let we are given a polynomial function as:
and we are aksed to evaluate this polynomial at 
Then the value of the polynomial will be:

Hence on evaluating the polynomial function f(x) at
we get the value of the polynomial function as
.
50/x
