#### Addition of Vectors

A vector is the displacement from point A to point B. Now consider a situation in which a girl moves from A to B and then from B to C. The net displacement done by the girl from point A to point C is given by the vector and expressed as vector AC = vector AB + vector AC. This is known as the triangle rule of vector addition. In general, if we have two vectors to add, they are positioned so that the starting point of one coincides with the terminal point of the other.

##### Multiplication of a Vector by a Scalar

Let **a** be a vector and let k be a scalar. So, the scalar denotes the product of the vector, because k**a** is called multiplication of the vector by the scalar. Note that k**a** is also a vector, consisting of a vector. The vector has only one direction (or vice versa), depending on whether the value of the vector is positive (or negative). Furthermore, the magnitude of the vector is several times greater than the magnitude of the vector.

###### Section formula

P and Q are represented by two points, representing OP and OQ, respectively, with respect to the original O. Subsequently, the line segment joining the points P and Q can be divided by the third point, R says, in two ways: internally and externally. Here, we intend to find the position vector for point R with respect to the origin O.
