## Integermania!

#### Jan Hus

Jan Hus was a church reformer who lived and worked in Prague, but was executed on 6 July 1415 by the church authorities because of his teachings. If we write this date in European format, ignoring the century, we have the date 6.7.15. Using one copy each of the digits 1, 5, 6, and 7, and any standard operations, create each of the positive integers. All four numbers must be used, but no others. Your solutions will be assigned an exquisiteness level.
