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. So far, only those solutions using the digits 2, 0, 1, and 0 in that order have been published. Student solutions were submitted January 1, 2010 through February 1, 2010. Submissions for missing numbers can still be submitted using the Web form. Rules: use the digits in the year 2010 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.
