Think about the fraction 24/7. - Doctor Peterson, The Math Forum http://mathforum.org/dr.math/ Date: 02/12/2002 at 16:59:05 From: Doctor Schwa Subject: Re: Very hard This is a really hard one! As a hint, here's how it works with 5,5,5,1: 5 * (5 - 1/5) = 24. Can you see a similar pattern that might work with your four numbers? - Doctor Schwa, The Math Forum http://mathforum.org/dr.math/ |
