Vector addition is a mathematical operation defined for vectors, which are quantities that have both magnitude and direction. When we add two vectors, a and b, we consider their magnitudes and directions to obtain a resultant vector.

To add vectors, we perform the following steps:
1. Place the initial point of vector b at the terminal point of vector a.
2. Draw the resultant vector, denoted as a + b, by connecting the initial point of vector a to the terminal point of vector b.

The resultant vector, a + b, represents the vector sum of a and b. The magnitude of the resultant vector depends on the magnitudes and the angle between a and b, while the direction is determined by the angle and orientation.

In terms of components, if a = (a1, a2) and b = (b1, b2), we can add the vectors component-wise:
a + b = (a1 + b1, a2 + b2)

Note that vector addition follows the commutative property, meaning the order in which we add the vectors does not affect the result:
a + b = b + a

Also, vector addition satisfies the associative property, which means that the grouping of vectors being added does not change the result:
(a + b) + c = a + (b + c)

Furthermore, the zero vector (0,0) serves as the additive identity, meaning that when added to any vector, it does not change the vector:
a + (0, 0) = a

These properties make vector addition a fundamental operation in vector algebra and find application in many mathematical and physical contexts.
