 This Web page is intended to record solutions submitted by students in grades three through twelve. Submissions will be posted starting February 1, 2005. Rules: use the digits in the year 2005 and the operations of +, -, x, ÷, sqrt (square root), ^ (raise to a power), and ! (factorial), along with grouping symbols, to write expressions for the counting numbers 1 through 100. Please read and follow the rules carefully.
