| Objective: | Produce the integers 1-100 using only combinations of 6 fives and the mathematical operations: +, –, *, / and !. |
| You may adjoin 5s together, so the number 55 is a possible combination of 2 5s. | |
| You may also use the operation !!, a double factorial. (Note: 5!! = 5*3*1 = 15.) | |
| Note: | I am still looking for a way to express the numbers 64 and 88 using only the operations +, –, *, / and !. |
| If you find a way, please send me an e-mail at wgarner [at] ucsd [dot] edu. |
