Hi there,
In a nutshell...
Many of the laws of ordinary algebra hold also for vector algebra. These laws are:
Commutative Law for Addition: A + B = B + A
Associative Law for Addition: A + (B + C) = (A + B) + C
The verification of the Associative law is shown below.
If we add A and B we get a vector E. And similarly if B is added to C , we get F .
Now D = E + C = A + F. Replacing E with
(A + B) and F with (B + C), we get
(A +B) + C = A + (B + C) and we see that the law is verified.
Stop now and make sure that you follow the above proof.
If so then you shouldn't have any further issues.
If you still aren't sure or are stuck on something in particular then please feel free to e-Mail me at melanieharvey81@hotmail.com and I will give you all the help I can!
Take Care
