The MCAT will test your ability to analyze single vectors, as well as solving larger problems combining 2 or more vectors. While the math for adding and subtracting vectors isn't difficult, it's important to understand the nature of each vector combination and the logic behind the specific equations used.
The video below shows you how to combine vectors when they are facing the same or opposite directions, as well as vectors pointing in completely different directions.
