Five Fives
Extending the idea of Four Fours, where the intention is to write each integer as a combination of 4 4's (any mathematical symbol is allowed except for digits that are not 4), we can create the game of Five Fives.
Write each integer as a combination of 5 5's - no other numerical digits allowed.
