Question

Vectors

Answer 1

Given vectors A, B, and C
if A + B = C
does C - B = A ?

Answer 2

Yes

Answer 3

Will you draw a picture of three vectors illustrating it?

Answer 4

you know, a+b =c

Answer 5

when you change the direction of b, you need to add - to b, so it becomes -b
consider the triangle again,
c+(-b) =a
so, c-b=a
