Given the question: Mathematics Made Difficult -  Mathematics Made Difficult is a book by Carl E. Linderholm that uses advanced mathematical methods to prove results normally shown using elementary proofs. Although the aim is largely satirical it also shows the non-trivial mathematics behind operations normally considered obvious such as numbering counting and factoring integers.As an example the proof that two is a prime number starts:It is easily seen that the only numbers between 0 and 2 including 0 but excluding 2 are 0 and 1.
