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.
