To find a - b geometrically with both tails at one point, the arrow a - b runs from where?
ATail of a to tail of b
BHead of a to head of b
CHead of b to head of a
DTail of b to head of b
Answer & Solution
Correct answer: C. Head of b to head of a
The arrow from the head of b to the head of a represents (-b) + a, which equals a - b.
