2008 Mathematics Game

Are you ready for a challenge? Join us for the 2008 Mathematics Game. Here are the rules:

Use the digits in the year 2008 and the operations +, -, x, ÷, sqrt (square root), ^ (raise to a power), and ! (factorial) — along with parentheses, brackets, or other grouping symbols — to write expressions for the counting numbers 1 through 100.

  • All four digits must be used in each expression.
  • Only the digits 2, 0, 0, 8 may be used.
  • Multi-digit numbers such as 20, 208, or .02 MAY be used this year.
  • The square function may NOT be used.
  • The integer function may NOT be used.

By definition:
0! = 1
[See Dr. Math’s Why does 0 factorial equal 1?]

For this game we will accept the value:
{0}^{0} = 1
[See the Dr. Math FAQ 0 to the 0 power.]
