Prove that:
((((a + b) + c) + d) + e) + f = ((a + b) + (c + d)) + (e + f)
The following properties may be helpful:
- (a + b) + c = a + (b + c)
- (a + b) + c = a + (b + c)
if a = b, then a + c = b + c
if the following are true:
- a = b
- b = c
then a = c
Please write your proof in the table below. Each row should contain one claim. The last claim is the statement that you are trying to prove.
