 Description: An ideal contains 0. (Contributed by Jeff Madsen, 10-Jun-2010.)
Hypotheses
Ref Expression
idl0cl.1 𝐺 = (1st𝑅)
idl0cl.2 𝑍 = (GId‘𝐺)
Assertion
Ref Expression
idl0cl ((𝑅 ∈ RingOps ∧ 𝐼 ∈ (Idl‘𝑅)) → 𝑍𝐼)

Proof of Theorem idl0cl
Dummy variables 𝑥 𝑦 𝑧 are mutually distinct and distinct from all other variables.
