Variables

Explanation
The Word Variable means something which can change.

Many times, we experience some events/situtation whose values are different, like number of days in a month, height of persons, length of roads, etc.

In Mathematics, to represent such values we attach a symbols to them, for example, length and breath of a rectangle is represented as l and b respectively. Here, l and b doesn't carry any particular values and so they are called Variables

The Value of a Variable is not fixed. Variable can have different values in different situations.
