The birthday of Integermania Master Jonathan Frank is November 4, 1990. Using one copy each of the numbers 4, 11, 19, and 90, and any standard operations, create each of the positive integers. All four numbers must be used, but no others. Also, the two-digit numbers 11, 19, and 90 may not be broken up. Your solutions will be assigned an exquisiteness level.
Use the online submissions page to get your Integermania solutions posted here! Five "new" or "improved" solutions per person per month are accepted.
