Multiplication of a Vector by a Number

Q. What result do we get if a Vector is multiplied by a number?

Multiplication of a Vector by a Number

If a Vector is multiplied by a number then its value increases in the same ratio i.e. if we multiply a vector by 2, then the value of the vector becomes twice but the direction remains the same. But if we multiply a Vector by a negative number then its value increases but the direction changes.
