I think we may assume commutativity, associativity, distributivity. Here is a simple example with 2 variables: P(x,y) = 2 + 2xy + x^2 + y^2. Letting x^2 = y^2 = 0 and then x = y = 1, the answer is 4. This is the number I am after in this particular example. Emeric
Are we to assume x,y,z,w are members of some kind of ring?

<< I am interested in an analytic device to handle the following simple situation. I have a polynomial P in several variables, x,y,z,u, say. It is of degree 2 in each variable. I would like to evaluate the polynomial when x^2 = 0, y^2 = 0, z^2 = 0, u^2 = 0 BUT x=y=z=u=1. Many thanks for any comment, hint, input.
