Challenging Puzzle Similar to the Four 4'sDate: 04/06/2006 at 01:22:24 From: Sam Subject: Math puzzle I've been looking all over for the solution to this problem: "Using only two 2's and any of the standard mathematical symbols, write an expression whose value is equal to exactly five." It must involve a greater knowledge of mathematics than I possess! Date: 04/06/2006 at 14:46:09 From: Doctor Douglas Subject: Re: Math puzzle Hi Sam. That's a tricky one! My solution uses, in addition to the two twos, a decimal point, a minus sign, and a square root. Hopefully that gives you enough of a hint to have the pleasure of figuring it out on your own. - Doctor Douglas, The Math Forum http://mathforum.org/dr.math/ |
