Let's prove the following theorem:

if the following are true:

then a + b = e

Given

1	a = 0
2	b = e

Proof Table

#	Claim	Reason
1	a + b = 0 + e	if a = 0 and b = e, then a + b = 0 + e (Equality Example)
2	0 + e = e	0 + e = e (Additive Identity Variation)
3	a + b = e	if a + b = 0 + e and 0 + e = e, then a + b = e (Transitive Property of Equality)
