Abstract
It is easy to list the various types of numbers and the various properties of numbers than to define the actual numbers themselves. Integers include the natural numbers, their negative counterparts, and the number 0, or zero. One visual representation of integers is the set of markings made on one of the axes for drawing graphs in coordinate geometry. A vector quantity is completely specified by a numerical value and a direction. One example of such a quantity is a displacement, which is completely specified by a distance moved and the direction of motion. The vector sum of two displacements represents the result of one displacement followed by the other. Relevance is attached to the sum of other vector quantities. The concept of vector sum has importance for any type of vector quantity. To distinguish scalar quantities from vector quantities, those quantities that are specified by a numerical value only are called scalar quantities. For example, distance and speed are scalar quantities, whereas displacement and velocity are vector quantities.
