Set a number to check. The cat will tell you whether the number is divisible by several divisors (up to this same number). Check out the use of the "FLOOR" and the "MOD". 1. Should the cat check ALL divisors smaller than the number? When can he stop? Change the script. 2. Create a script that could do the opposite: ask the user whether a number (provided by the cat) is divisible by several numbers (also provided by the cat). When the user answers "yes" or "no", the cat should check whether this answer is correct.
