Description: Rotation law for the adder carry. (Contributed by Mario Carneiro, 4-Sep-2016.)

Assertion

Ref	Expression
cadrot	⊢ (cadd(𝜑, 𝜓, 𝜒) ↔ cadd(𝜓, 𝜒, 𝜑))

Proof of Theorem cadrot

Step	Hyp	Ref	Expression
1		cadcoma 1645	. 2 ⊢ (cadd(𝜑, 𝜓, 𝜒) ↔ cadd(𝜓, 𝜑, 𝜒))
2		cadcomb 1646	. 2 ⊢ (cadd(𝜓, 𝜑, 𝜒) ↔ cadd(𝜓, 𝜒, 𝜑))
3	1, 2	bitri 278	1 ⊢ (cadd(𝜑, 𝜓, 𝜒) ↔ cadd(𝜓, 𝜒, 𝜑))
