How to Add Vectors

In linear algebra, vectors represent an ordered sequence of numbers. You can add two or more vectors by adding the corresponding components together.

The sum of two vectors is referred to as the resultant vector. You can also subtract vectors in a similar fashion.

Vector Addition Formula

So, the vector addition formula is as follows:

a + b = ({xa + xb}, {ya + yb}, {za + zb})

Thus, vector a + b is equal to the sum of the x coordinates of each vector, the sum of the y coordinates of each vector, and the sum of the z coordinates of each vector.

Parallelogram Method

You can also add vectors a and b using the parallelogram method.

Using this method, place the two vectors at the same initial point. Then, complete the parallelogram by drawing two additional lines.

The diagonal of the parallelogram is equal to the resultant vector a + b.
