ok first of all you need to know the difference between numerical and variable expressions.. Numerical expressions involve numbers associated with the help of some algebraic operation (+,-,*,/...) e.g. 5+3, 3/3 etc While variable expressions involve variables (denoted by alphabets usually)...a variable can take any numerical value...e.g x+3 (here x is a variable) (x can be any number)
