Someone please help!

I have to write a stand-alone text- based calculator that can perform subtraction, addition, multiplication, and division. In addition, the calculator has to be able to perform the following calculations:

1) Square a number (n*n),
2) Find the square root of a number,
3) Add a memory store,
4) Add a memory recall,
5) Find the nth number in the Fibonacci sequence,
6) Find n factorial,
7) Trap for divide by 0.

So for example, if the user enters:

A 4 5

your program will print:

4+5=9

My program also has to have a help function!

I really hope that someone can help me because that would be great!
