In class VI the students were discussing about the Algebraic Expression. It can be formed from variables, which are obtained by basic operators (+,-, x and ÷) on variables. It is mostly used to solve a word problem by translating the word statement to that statement in the symbols of algebra. On the basis of above information answer the following:
