Five Digits
Submitted by Brijesh Dave
Can you arrange the five digits, 1, 2, 3, 4, and 5 in such a way that,
with the aid of some mathematical symbols, you can obtain the four numbers: 111, 222, 333,
and 999?
You must use each of the five digits exactly once but in any order.
You may use any of the math symbols or functions:
addition (+), subtraction (-), multiplication (x), division (/), exponentiation (^), factorials (!), and parentheses ().
