When adding two vectors graphically, a+b=c. Does b+a produce the same resultant vector c?
Yes, two vectors added together always produce the same resultant vector
No, because order matters
Yes, but c will be pointing in the opposite direction
No, because you can't add two vectors

Yes, two vectors subtracted together always produce the same resultant vector
No, because order matters
Yes, but c will be pointing in the opposite direction
No, because you can't subtract two vectors
