I am trying to read a book about vector spaces, without taking introductory courses about linear algebra to be rigorous from start. Any way I stumbled across
this proof
and my problem is in proof b.
cant he use vs 6. what prevents him from doing so.
then (-a)x = (-1 * a)x = -(ax) = (a * -1)x = a(-x)
what is error in my proof so he didnt use it
