The operations of numbers progress from left to right.                        Rules: If an even number is followed by a prime number, then they are to be multiplied. If an even number is followed by a composite odd number, then the odd number is to be subtracted from the even number.                                         If a composite odd number is followed by a prime number, then the first number is to be divided by the second number.                                              If an odd number is followed by an even number which is a perfect square, then they are to be added.                                                            If an odd number is followed by another odd number, then they are to be added.
