A Math Forum Project

Math Forum || K-12 Math Puzzles || Problems of the Week || Student Center

This Web page is intended to record solutions submitted by students in grades three through twelve. Student solutions were submitted January 1, 2005 through February 1, 2005. Submissions for missing numbers can still be submitted using the Web form. 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. Teachers may print out worksheets for students to record their findings, or print sheets of manipulatives for students to use.
