Webmulas over rings (and fields). Specifically, assume that the arithmetic formulas Φ 1,Φ 2 compute the same polynomial in F[x 1,...,x n]. An equational proof of Φ 1 = Φ 2 is a se-quence of equations, terminating with the equation Φ 1 = Φ 2, starting from polynomial-ring axioms, and identities like ϕ = ϕ, and such that every other ...
