Rules:
(i) If a 2-digit even number is followed by another even number, then the first one is to be divided by the second one.

(iii) If an odd number is followed by another odd number, then the two are to be added.
(iv) If a 3-digit number is followed by a 2-digit number which is a perfect square, then the second number is to be subtracted from the first number.
