This arrow is what we call a vector!</p> <p><img src="https://thefarahstack.com/images/posts/vectors-arrow-basic.png" alt="An arrow a.k.a Vector"></p> <p>The vector essentially is comprised of:</p> <ul> <li>Length (also called magnitude or size)</li> <li>Direction (which way it&rsquo;s pointing)</li> </ul> <p><img src="https://thefarahstack.com/images/posts/vectors-multiple-example.png" alt="Multiple vectors representing their magnitude and direction"></p> <p>You&rsquo;re thinking sure it looks like a bunch of mathematics, what does that have to do with me living my life? There are real-life situations that these vectors represent. One such example that most people recognize is Maps.</p>
