basic code, only had the software for two days! easy to use, multipfunctional calculater uses "GOTO" and "THEN" and "IF" lots of times

easy to understand code, but effective . th first number determines the operation that the calcuoater does. then the first and second numbers determine the numbers that the calculater aplies the function
