Do you know what is it and what is the role of variable in algebra? The first answer that we will receive if we ask what is a variable to the students is “x or y or z”.  This is the common answer we will receive from all the students. Then suppose if we ask what is the meaning of the variable, for this there will be no answer with them. This happens generally with most of the students. This shows that they are lack in basics which means that they don’t know the meanings of some important words that we use in math. Without knowing the meanings if the students study also there will no use. Because, they don’t know exactly where and how to use that word.
