I have an expression in x and y.
I have specific values of x and y for which I need to evaluate the expression.
How do I write the command?

(* from a second post *)

I just posted a query, and I have another problem.
Now mathematica is doing something it shouldn't be doing.
When I put in an expression such as
i = 3 x^2 + 2 y^2 - 4 y + 1

it should just reprint the expression on the next line.

But now it's putting out a numerical expression.

I've tried using the "clear" command for i, also for x and y, but it just keeps doing it.
