  In the solution, it states that 59 and 45 have a difference of 7. This is clearly wrong. It should have stated "For choice ii.), 59 and 45 have a difference of 14, which is a multiple of 7, so this is the correct answer."

  @professionalbronco Yeah! This trick makes finding remainders when dividing by 9 really fast. It's not too common that a problem will require you to find a number \(\pmod{9}\), but it's definitely very useful for this specific case.
