Problem of the Month
Easy as 1, 2, 3!
Mr. P wants to build a clock in which the twelve numbers on the face are written as expressions of 1, 2, and 3.
The numbers 1, 2, and 3 must be used in order in each expression.
You may use
operations +, -, x, ÷ (or / for
divided by), ^ (raised to a power),
sqrt (square root), ! (factorial),
and int
(or [ ] for greatest integer function),
along with grouping symbols.
For example, the number zero could have been written as 1 + 2 - 3.
