Theorem sadeq 15032

Description: Any element of a sequence sum only depends on the values of the argument sequences up to and including that point. (Contributed by Mario Carneiro, 9-Sep-2016.)

Hypotheses

sadeq.a	⊢ (𝜑 → 𝐴 ⊆ ℕ0)
sadeq.b	⊢ (𝜑 → 𝐵 ⊆ ℕ0)

Assertion

Ref	Expression
sadeq	⊢ (𝜑 → ((𝐴 sadd 𝐵) ∩ (0..^𝑁)) = (((𝐴 ∩ (0..^𝑁)) sadd (𝐵 ∩ (0..^𝑁))) ∩ (0..^𝑁)))

Proof of Theorem sadeq

Dummy variables 𝑚 𝑐 𝑛 are mutually distinct and distinct from all other variables.
