This page shows solutions that arrived from February 26 till March 12, 2001.

Solution Tips: A technique to help you form expressions is to use a lesser known fact that "0!" (zero factorial) is equal to "1". That is, 0! = 1. [See #90 and #93 below.]

Also, we now announce the permission to use another math function: logarithms. For those who wish to use it, writing "log(n)" will mean the "common logarithm of  'n' ". The base of 10 will be assumed and will not count as using the digits "1" and "0". [See #100 below.]

A Notice about Postings: Beginning with this page of solutions, we wish to limit the number of solutions that one individual may present to 2 solutions per page. This is to encourage wider participation of students and schools. We are receiving so many solutions in general. You may, of course, continue to send more solutions to be presented on a future page. Thank you for your understanding.
